leukotriene A-4 hydrolase/aminopeptidase; Members of this family represent a distinctive subset within the zinc metallopeptidase family M1 (pfam01433). The majority of the members of pfam01433 are aminopeptidases, but the sequences in this family for which the function is known are leukotriene A-4 hydrolase. A dual epoxide hydrolase and aminopeptidase activity at the same active site is indicated. The physiological substrate for aminopeptidase activity is not known.

Peptidase M1 family including Leukotriene A4 hydrolase catalytic domain; This model represents the N-terminal catalytic domain of leukotriene A4 hydrolase (LTA4H; E.C. 3.3.2.6) and the close homolog cold-active aminopeptidase (Colwellia psychrerythraea-type peptidase; ColAP), both members of the aminopeptidase M1 family. LTA4H is a bifunctional enzyme, possessing an aminopeptidase as well as an epoxide hydrolase activity. The two activities occupy different, but overlapping sites. The activity and physiological relevance of the aminopeptidase is poorly understood while the epoxide hydrolase converts leukotriene A4 (LTA4) into leukotriene B4 (LTB4), a potent chemotaxin that is fundamental to the inflammatory response of mammals. It accepts a variety of substrates, including some opioid, di- and tripeptides, as well as chromogenic aminoacyl-p-nitroanilide derivatives. The aminopeptidase activity of LTA4H is possibly involved in the processing of peptides related to inflammation and host defense. Kinetic analysis shows that LTA4H hydrolyzes arginyl tripeptides with high efficiency and specificity, indicating its function as an arginyl aminopeptidase. Thermodynamic characterization using different biophysical methods shows that structurally distinct inhibitors of the LTA4H occupy different regions of the binding site; while some (RB202, ARM1 and SC57461A) bind to the hydrophobic hydrolase side, both bestatin and captopril are located at the hydrophilic peptidase side. LTB4H overexpression is associated with different pathological conditions and diseases such as cystic fibrosis, coronary heart disease, sepsis, shock, connective tissue disease, and chronic obstructive pulmonary disease. It is also overexpressed in certain human cancers, and has been identified as a functionally important target for mediating anticancer properties of resveratrol, a well-known red wine polyphenolic compound with cancer chemopreventive activity.

Peptidase M1 family including Leukotriene A4 hydrolase catalytic domain; This model represents the N-terminal catalytic domain of leukotriene A4 hydrolase (LTA4H; E.C. 3.3.2.6) and the close homolog cold-active aminopeptidase (Colwellia psychrerythraea-type peptidase; ColAP), both members of the aminopeptidase M1 family. LTA4H is a bifunctional enzyme, possessing an aminopeptidase as well as an epoxide hydrolase activity. The two activities occupy different, but overlapping sites. The activity and physiological relevance of the aminopeptidase is poorly understood while the epoxide hydrolase converts leukotriene A4 (LTA4) into leukotriene B4 (LTB4), a potent chemotaxin that is fundamental to the inflammatory response of mammals. It accepts a variety of substrates, including some opioid, di- and tripeptides, as well as chromogenic aminoacyl-p-nitroanilide derivatives. The aminopeptidase activity of LTA4H is possibly involved in the processing of peptides related to inflammation and host defense. Kinetic analysis shows that LTA4H hydrolyzes arginyl tripeptides with high efficiency and specificity, indicating its function as an arginyl aminopeptidase. Thermodynamic characterization using different biophysical methods shows that structurally distinct inhibitors of the LTA4H occupy different regions of the binding site; while some (RB202, ARM1 and SC57461A) bind to the hydrophobic hydrolase side, both bestatin and captopril are located at the hydrophilic peptidase side. LTB4H overexpression is associated with different pathological conditions and diseases such as cystic fibrosis, coronary heart disease, sepsis, shock, connective tissue disease, and chronic obstructive pulmonary disease. It is also overexpressed in certain human cancers, and has been identified as a functionally important target for mediating anticancer properties of resveratrol, a well-known red wine polyphenolic compound with cancer chemopreventive activity.

20-431 5.05e-162

Peptidase M1 family includes the catalytic domains of aminopeptidase N and leukotriene A4 hydrolase; The model represents the catalytic domains of M1 peptidase family members including aminopeptidase N (APN) and leukotriene A4 hydrolase (LTA4H). All peptidases in this family bind a single catalytic zinc ion which is tetrahedrally co-ordinated by three amino acid ligands and a water molecule that forms the nucleophile upon activation during catalysis. APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and is present in a variety of human tissues and cell types. APN expression is dysregulated in many inflammatory diseases and is enhanced in numerous tumor cells, making it a lead target in the development of anti-cancer and anti-inflammatory drugs. LTA4H is a bifunctional enzyme, possessing an aminopeptidase as well as an epoxide hydrolase activity. The two activities occupy different, but overlapping sites. The activity and physiological relevance of the aminopeptidase in LTA4H is as yet unknown, while the epoxide hydrolase converts leukotriene A4 (LTA4) into leukotriene B4 (LTB4), a potent chemotaxin that is fundamental to the inflammatory response of mammals.

20-450 1.92e-71

Peptidase M1 family similar to aminopeptidase N catalytic domain; This family contains mostly bacterial and some archaeal M1 peptidases with smilarity to the catalytic domain of aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease belonging to the M1 gluzincin family. APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and, in higher eukaryotes, is present in a variety of human tissues and cell types (leukocyte, fibroblast, endothelial and epithelial cells). APN expression is dysregulated in inflammatory diseases such as chronic pain, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, systemic lupus erythematosus, polymyositis/dermatomyosytis and pulmonary sarcoidosis, and is enhanced in tumor cells such as melanoma, renal, prostate, pancreas, colon, gastric and thyroid cancers. It is predominantly expressed on stem cells and on cells of the granulocytic and monocytic lineages at distinct stages of differentiation, thus considered a marker of differentiation. Thus, APN inhibition may lead to the development of anti-cancer and anti-inflammatory drugs. APNs are also present in many pathogenic bacteria and represent potential drug targets. Some APNs have been used commercially, such as one from Lactococcus lactis used in the food industry. APN also serves as a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs have also been extensively studied as putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.

21-444 1.10e-53

Peptidase M1 aminopeptidase N catalytic domain family which includes aminopeptidase N (APN), aminopeptidase Q (APQ), tricorn interacting factor F3, and endoplasmic reticulum aminopeptidase 1 (ERAP1); This M1 peptidase family includes eukaryotic and bacterial members: the catalytic domains of aminopeptidase N (APN), aminopeptidase Q (APQ, laeverin), endoplasmic reticulum aminopeptidase 1 (ERAP1) as well as tricorn interacting factor F3. Aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease, preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and is present in a variety of human tissues and cell types (leukocyte, fibroblast, endothelial and epithelial cells). APN expression is dysregulated in inflammatory diseases such as chronic pain, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, systemic lupus erythematosus, polymyositis/dermatomyosytis and pulmonary sarcoidosis, and is enhanced in tumor cells such as melanoma, renal, prostate, pancreas, colon, gastric and thyroid cancers. It is considered a marker of differentiation since it is predominantly expressed on stem cells and on cells of the granulocytic and monocytic lineages at distinct stages of differentiation. Thus, APN inhibition may lead to the development of anti-cancer and anti-inflammatory drugs. ERAP1, also known as endoplasmic reticulum aminopeptidase associated with antigen processing (ERAAP), adipocyte derived leucine aminopeptidase (A-LAP), or aminopeptidase regulating tumor necrosis factor receptor I (THFRI) shedding (ARTS-1), associates with the closely related ER aminopeptidase ERAP2, for the final trimming of peptides within the ER for presentation by MHC class I molecules. ERAP1 is associated with ankylosing spondylitis (AS), an inflammatory arthritis that predominantly affects the spine. ERAP1 also aids in the shedding of membrane-bound cytokine receptors. The tricorn interacting factor F3, together with factors F1 and F2, degrades the tricorn protease products, producing free amino acids, thus completing the proteasomal degradation pathway. F3 is homologous to F2, but not F1, and shows a strong preference for glutamate in the P1' position. APQ, also known as laeverin, is specifically expressed in human embryo-derived extravillous trophoblasts (EVTs) that invade the uterus during early placentation. It cleaves the N-terminal amino acid of various peptides such as angiotensin III, endokinin C, and kisspeptin-10, all expressed in the placenta in large quantities. APN is a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs are also putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.

52-448 8.92e-48

Peptidase M1 family including aminopeptidase N catalytic domain; This model represents the catalytic domain of bacterial and eukaryotic aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease belonging to the M1 gluzincin family. APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and, in higher eukaryotes, is present in a variety of human tissues and cell types (leukocyte, fibroblast, endothelial and epithelial cells). APN expression is dysregulated in inflammatory diseases such as chronic pain, rheumatoid arthritis, multiple sclerosis, systemic sclerosis, systemic lupus erythematosus, polymyositis/dermatomyosytis and pulmonary sarcoidosis, and is enhanced in tumor cells such as melanoma, renal, prostate, pancreas, colon, gastric and thyroid cancers. It is predominantly expressed on stem cells and on cells of the granulocytic and monocytic lineages at distinct stages of differentiation, thus considered a marker of differentiation. Thus, APN inhibition may lead to the development of anti-cancer and anti-inflammatory drugs. APNs are also present in many pathogenic bacteria and represent potential drug targets. Some APNs have been used commercially, such as one from Lactococcus lactis used in the food industry. APN also serves as a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs have also been extensively studied as putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.

235-329 1.97e-29

Gluzincin Peptidase family (thermolysin-like proteinases, TLPs) which includes peptidases M1, M2, M3, M4, M13, M32 and M36 (fungalysins); The Gluzincin family (thermolysin-like peptidases or TLPs) includes several zinc-dependent metallopeptidases such as M1, M2, M3, M4, M13, M32, M36 peptidases (MEROPS classification), which contain the HEXXH motif as part of their active site. Peptidases in this family bind a single catalytic zinc ion which is tetrahedrally co-ordinated by three amino acid ligands and a water molecule that forms the nucleophile on activation during catalysis. The M1 family includes aminopeptidase N (APN) and leukotriene A4 hydrolase (LTA4H). APN preferentially cleaves neutral amino acids from the N-terminus of oligopeptides and is present in a variety of human tissues and cell types. LTA4H is a bifunctional enzyme, possessing an aminopeptidase as well as an epoxide hydrolase activity such that the two activities occupy different, but overlapping sites. The M3_like peptidases include the M2_ACE, M3 or neurolysin-like family (subfamilies M3B_PepF and M3A) and M32_Taq peptidases. The M2 peptidase angiotensin converting enzyme (ACE, EC 3.4.15.1) catalyzes the conversion of decapeptide angiotensin I to the potent vasopressor octapeptide angiotensin II. ACE is a key component of the renin-angiotensin system that regulates blood pressure, thus ACE inhibitors are important for the treatment of hypertension. M3A includes thimet oligopeptidase (TOP; endopeptidase 3.4.24.15), neurolysin (3.4.24.16), and the mitochondrial intermediate peptidase; and M3B includes oligopeptidase F. The M32 family includes eukaryotic enzymes from protozoa Trypanosoma cruzi, a causative agent of Chagas' disease, and from Leishmania major, a parasite that causes leishmaniasis, making these enzymes attractive targets for drug development. The M4 family includes secreted protease thermolysin (EC 3.4.24.27), pseudolysin, aureolysin, and neutral protease as well as bacillolysin (EC 3.4.24.28) that degrade extracellular proteins and peptides for bacterial nutrition, especially prior to sporulation. Thermolysin is widely used as a nonspecific protease to obtain fragments for peptide sequencing as well as in production of the artificial sweetener aspartame. The M13 family includes neprilysin (EC 3.4.24.11) and endothelin-converting enzyme I (ECE-1, EC 3.4.24.71), which fulfill a broad range of physiological roles due to the greater variation in the S2' subsite allowing substrate specificity and are prime therapeutic targets for selective inhibition. The peptidase M36 fungalysin family includes endopeptidases from pathogenic fungi. Fungalysin hydrolyzes extracellular matrix proteins such as elastin and keratin. Aspergillus fumigatus causes the pulmonary disease aspergillosis by invading the lungs of immuno-compromised animals and secreting fungalysin that possibly breaks down proteinaceous structural barriers.

Peptidase M1 family similar to aminopeptidase N catalytic domain; This family contains bacterial M1 peptidases with smilarity to the catalytic domain of aminopeptidase N (APN; CD13; alanyl aminopeptidase; EC 3.4.11.2), a type II integral membrane protease belonging to the M1 gluzincin family.

Some APNs have been used commercially, such as one from Lactococcus lactis used in the food industry. APN also serves as a receptor for coronaviruses, although the virus receptor interaction site seems to be distinct from the enzymatic site and aminopeptidase activity is not necessary for viral infection. APNs have also been extensively studied as putative Cry toxin receptors. Cry1 proteins are pore-forming toxins that bind to the midgut epithelial cell membrane of susceptible insect larvae, causing extensive damage. Several different toxins, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca and Cry1Fa, have been shown to bind to APNs; however, a direct role of APN in cytotoxicity has been yet to be firmly established.

TATA binding protein (TBP) associated factor 2; This family includes TATA binding protein (TBP) associated factor 2 (TAF2, TBP-associated factor TAFII150, transcription initiation factor TFIID subunit 2, RNA polymerase II TBP-associated factor subunit B), and has homology to the M1 gluzincin family. TAF2 is part of the TFIID multidomain subunit complex essential for transcription of most protein-encoded genes by RNA polymerase II. TAF2 is known to interact with the initiator element (Inr) found at the transcription start site of many genes, thus possibly playing a key role in promoter binding as well as start-site selection. Image analysis has shown TAF2 to form a complex with TAF1 and TBP, inferring its role in promoter recognition. Peptidases in the M1 family bind a single catalytic zinc ion which is tetrahedrally co-ordinated by three amino acid ligands and a water molecule that forms the nucleophile on activation during catalysis. TAF2, however, lacks these active site residues.
