Globin-like protein superfamily; This globin-like domain superfamily contains a wide variety of all-helical proteins that bind porphyrins, phycobilins, and other non-heme cofactors, and play various roles in all three kingdoms of life, including sensors or transporters of oxygen. It includes the M/myoglobin-like, S/sensor globin, and T/truncated globin (TrHb) families, and the phycobiliproteins (PBPs). The M family includes chimeric (FHbs/flavohemoglobins) and single-domain globins: FHbs, Ngbs/neuroglobins, Cygb/cytoglobins, GbE/avian eye specific globin E, GbX/globin X, amphibian GbY/globin Y, Mb/myoglobin, HbA/hemoglobin-alpha, HbB/hemoglobin-beta, SDgbs/single-domain globins related to FHbs, and Adgb/androglobin. The S family includes GCS/globin-coupled sensors, Pgbs/protoglobins, and SSDgbs/sensor single domain globins. The T family is classified into three main groups: TrHb1s (N), TrHb2s (O) and TrHb3s (P). The M- and S families exhibit the canonical secondary structure of hemoglobins, a 3-over-3 alpha-helical sandwich structure (3/3 Mb-fold), built by eight alpha-helical segments (named A through H). For M family Adgbs, this globin domain is permuted, such that C-H are followed by A-B. The T family globins adopt a 2-on-2 alpha-helical sandwich structure, resulting from extensive and complex modifications of the canonical 3-on-3 alpha-helical sandwich that are distributed throughout the whole protein molecule. PBPs bind the linear tetrapyrrole chromophore, phycobilin, a prosthetic group chemically and metabolically related to iron protoporphyrin IX/protoheme. Examples of other globin-like domains which bind non-heme cofactors include those of the Bacillus anthracis sporulation inhibitors pXO1-118 and pXO2-61 which bind fatty acid and halide in vitro, and the globin-like domain of Bacillus subtilis RsbRA which is presumed to channel sensory input to the C-terminal sulfate transporter/ anti-sigma factor antagonist (STAT) domain. RsbRA is a component of the sigma B-activating stressosome, and a regulator of the RNA polymerase sigma factor subunit sigma (B).

 4-150 3.53e-95

Neuroglobins; The Ngb described in this subfamily is a hexacoordinated heme globin chiefly expressed in neurons of the brain and retina. In the human brain, it is highly expressed in the hypothalamus, amygdala, and in the pontine tegmental nuclei. It affords protection of brain neurons from ischemia and hypoxia. In rats, it plays a role in the neuroprotection of limb ischemic preconditioning (LIP). It plays roles as: a sensor of oxygen levels; a store or reservoir for oxygen; a facilitator for oxygen transport; a regulator of ROS; and a scavenger of nitric oxide. It also functions in the protection against apoptosis and in sleep regulation. This subgroup contains Ngb from mammalian and non-mammalian vertebrates, including fish, amphibians and reptiles; the functionally pentacoordinated acoelomorph Symsagittifera roscoffensis Ngb does not belong to this subgroup.

myoglobin-like; M family globin domain; This family includes chimeric (FHbs/flavohemoglobins) and single-domain globins: FHbs, Ngbs/neuroglobins, Cygb/cytoglobins, GbE/avian eye specific globin E, GbX/globin X, amphibian GbY/globin Y, Mb/myoglobin, HbA/hemoglobin-alpha, HbB/hemoglobin-beta, SDgbs/single-domain globins related to FHbs, and Adgb/androglobin. The M family exhibits the canonical secondary structure of hemoglobins, a 3-over-3 alpha-helical sandwich structure (3/3 Mb-fold), built by eight alpha-helical segments (named A through H). In Adgbs, the globin domain is split into two: helices C-H are followed by helices A-B and the two parts are separated by the IQ motif. Although rearranged, the globin domain of most Adgbs contains a number of conserved residues which play critical roles in heme-coordination and gas ligand binding. Adgbs have been omitted from this A-H helix cd.

 8-147 3.02e-25

Hell's gate globin I (HGbI) from Methylacidophilum infernorum and related proteins; HGbI is a single-domain heme-containing protein isolated from Methylacidiphilum infernorum, an aerobic acidophilic and thermophilic methanotroph. M. infernorum grows optimally at pH 2.0 and 60C and its home is New Zealand's Hell's Gate geothermal park. The physiological role of HGbI has yet to be determined. It has an extremely strong resistance to auto-oxidation, and has fast oxygen-binding/slow release characteristics. Its CO on-rate is comparable to the O2 on-rate, and it is able to bind acetate with high affinity in the ferric state. The coordination of the heme iron changes in the ferrous form from pentacoordinate at low pH to predominantly hexacoordinate at high pH; in the ferric form, it is predominantly hexacoordinate at all pH.

 4-149 4.03e-20

Globin_X (GbX); Zebrafish globin X (GbX) is expressed at low levels in neurons of the central nervous system, and appears to be associated with the sensory system. GbX is likely to be attached to the cell membrane via S-palmitoylation and N-myristoylation. It's unlikely to have a true respiratory function as it is membrane-associated. It has been suggested that it may protect the lipids in the cell membrane from oxidation or act as a redox-sensing or signaling protein. Zebrafish GbX is hexacoordinate, and displays cooperative O2 binding.

Caenorhabditis elegans globin GLB-25, and related globins; The C. elegans genome contains 33 genes encoding globins that are all transcribed. These are very diverse in gene and protein structure and are localized in a variety of cells. The C. elegans globin GLB-25 (locus tag T06A1.3), like the majority of them, was expressed in neuronal cells in the head and tail portions of the body and in the nerve cord.

 30-146 1.36e-14

Globin domain of uncharacterized oxidoreductases containing a FAD/NADH binding domain; This subfamily is composed of uncharacterized proteins containing an N-terminal myoglobin-like (M family globin) domain and a C-terminal oxygenase reductase FAD/NADH binding domain belonging to the ferredoxin reductase (FNR) family and is usually part of multi-component bacterial oxygenases which oxidize hydrocarbons using oxygen as the oxidant. The domain architecture of this subfamily is similar to flavohemoglobins, which function primarily as nitric oxide dioxygenases (NODs, EC 1.14.12.17), converting NO and O2 to inert NO3- (nitrate). They protect from nitrosative stress (the broad range of cellular toxicities caused by NO), and modulate NO signaling pathways. NO scavenging by flavoHb attenuates the expression of the nitrosative stress response, affects the swarming behavior of Escherichia coli, and maintains squid-Vibrio fischeri and Medicago truncatula-Sinorhizobium meliloti symbioses.

Class1 nonsymbiotic hemoglobins (nsHbs), class II nsHbs, leghemoglobins (Lbs,) and related proteins; Class1 nsHbs include the dimeric hexacoordinate Trema tomentosa nsHb and the dimeric hexacoordinate nsHb from monocot barley. Also belonging to this family is ParaHb, a dimeric pentacoordinate Hb from the root nodules of Parasponia andersonii, a non-legume capable of symbiotic nitrogen fixation. ParaHb is unusual in that it has different heme redox potentials for each subunit; it may have evolved from class1 nsHbs. Lbs are pentacoordinate, and facilitate the diffusion of O2 to the respiring Rhizobium bacteroids within root nodules. They may have evolved from class 2 nonsymbiotic hemoglobins (class2 nsHb).

Globin-like protein superfamily; This globin-like domain superfamily contains a wide variety of all-helical proteins that bind porphyrins, phycobilins, and other non-heme cofactors, and play various roles in all three kingdoms of life, including sensors or transporters of oxygen. It includes the M/myoglobin-like, S/sensor globin, and T/truncated globin (TrHb) families, and the phycobiliproteins (PBPs). The M family includes chimeric (FHbs/flavohemoglobins) and single-domain globins: FHbs, Ngbs/neuroglobins, Cygb/cytoglobins, GbE/avian eye specific globin E, GbX/globin X, amphibian GbY/globin Y, Mb/myoglobin, HbA/hemoglobin-alpha, HbB/hemoglobin-beta, SDgbs/single-domain globins related to FHbs, and Adgb/androglobin. The S family includes GCS/globin-coupled sensors, Pgbs/protoglobins, and SSDgbs/sensor single domain globins. The T family is classified into three main groups: TrHb1s (N), TrHb2s (O) and TrHb3s (P). The M- and S families exhibit the canonical secondary structure of hemoglobins, a 3-over-3 alpha-helical sandwich structure (3/3 Mb-fold), built by eight alpha-helical segments (named A through H). For M family Adgbs, this globin domain is permuted, such that C-H are followed by A-B. The T family globins adopt a 2-on-2 alpha-helical sandwich structure, resulting from extensive and complex modifications of the canonical 3-on-3 alpha-helical sandwich that are distributed throughout the whole protein molecule. PBPs bind the linear tetrapyrrole chromophore, phycobilin, a prosthetic group chemically and metabolically related to iron protoporphyrin IX/protoheme. Examples of other globin-like domains which bind non-heme cofactors include those of the Bacillus anthracis sporulation inhibitors pXO1-118 and pXO2-61 which bind fatty acid and halide in vitro, and the globin-like domain of Bacillus subtilis RsbRA which is presumed to channel sensory input to the C-terminal sulfate transporter/ anti-sigma factor antagonist (STAT) domain. RsbRA is a component of the sigma B-activating stressosome, and a regulator of the RNA polymerase sigma factor subunit sigma (B).

Globin domain of Saccharomyces cerevisiae flavohemoglobin (Yhb1p) and related domains; FlavoHbs function primarily as nitric oxide dioxygenases (NODs, EC 1.14.12.17), converting NO and O2 to inert NO3- (nitrate). They have an N-terminal globin domain and a C-terminal ferredoxin reductase-like NAD- and FAD-binding domain, and use the reducing power of cellular NAD(P)H to drive regeneration of the ferrous heme. They protect from nitrosative stress (the broad range of cellular toxicities caused by NO), and modulate NO signaling pathways. S. cerevisiae Yhb1p has been shown to protect against nitrosative stress and to control ferric reductase activity; it may participate in regulating the activity of plasma membrane ferric reductase(s). Also included in this subfamily is Dictyostelium discoideum FlavoHb, the expression of which affects D. discoideum development.

 8-150 1.04e-10

Hemoglobin beta, gamma, delta, epsilon, and related Hb subunits; Hb is the oxygen transport protein of erythrocytes. It is an allosterically modulated heterotetramer. Hemoglobin A (HbA) is the most common Hb in adult humans, and is formed from two alpha-chains and two beta-chains (alpha2beta2). An equilibrium exists between deoxygenated/unliganded/T(tense state) Hb having low oxygen affinity, and oxygenated /liganded/R(relaxed state) Hb having a high oxygen affinity. Various endogenous heterotropic effectors bind Hb to modulate its oxygen affinity and cooperative behavior, e.g. hydrogen ions, chloride ions, carbon dioxide and 2,3-bisphosphoglycerate. Hb is also an allosterically regulated nitrite reductase; the plasma nitrite anion may be activated by hemoglobin in areas of hypoxia to bring about vasodilation. Other Hb types are: HbA2 (alpha2delta2) which in normal individuals, is naturally expressed at a low level; Hb Portland-1 (zeta2gamma2), Hb Gower-1 (zeta2epsilon2), and Hb Gower-2 (alpha2epsilon2), which are Hbs present during the embryonic period; and fetal hemoglobin (HbF, alpha2gamma2), the primary hemoglobin throughout most of gestation. These Hbs types have differences in O2 affinity and in their interactions with allosteric effectors.

Cytoglobin and related globins; Cygb is a hexacoordinated heme-containing protein, able to bind O2, NO and carbon monoxide. It has both nitric oxide dioxygenase and lipid peroxidase activities, and potentially participates in the maintenance of normal phenotype by implementing a homeostatic effect, to counteract stress conditions imposed on a cell. Cygb is implicated in multiple human pathologies: it is up-regulated in fibrosis and neurodegenerative disorders, and down-regulated in multiple cancer types, and may have a tumor suppressor role. It is expressed ubiquitously across a broad range of vertebrate organs including liver, heart, brain, lung, retina, and gut. In the human brain, it was detected at high levels in the habenula, hypothalamus, thalamus, hippocampus and pontine tegmental nuclei, detected at a low level in the cerebral cortex, and undetected in the cerebellar cortex.

 4-139 1.35e-06

Globin domain of Alcaligenes eutrophus flavohemoglobin (FHP) and related proteins; Flavohemoglobins (flavoHbs) function primarily as nitric oxide dioxygenases (NODs, EC 1.14.12.17), converting NO and O2 to inert NO3- (nitrate). They have an N-terminal globin domain and a C-terminal ferredoxin reductase-like NAD- and FAD-binding domain, and use the reducing power of cellular NAD(P)H to drive regeneration of the ferrous heme. They protect from nitrosative stress (the broad range of cellular toxicities caused by NO), and modulate NO signaling pathways. NO scavenging by flavoHb maintains Medicago truncatula-Sinorhizobium meliloti symbiosis. Alcaligenes eutrophus FHP contains a phospholipid-binding site.

They have an N-terminal globin domain and a C-terminal ferredoxin reductase-like NAD- and FAD-binding domain, and use the reducing power of cellular NAD(P)H to drive regeneration of the ferrous heme. They protect from nitrosative stress (the broad range of cellular toxicities caused by NO), and modulate NO signaling pathways. NO scavenging by flavoHb attenuates the expression of the nitrosative stress response, affects the swarming behavior of Escherichia coli, and maintains squid-Vibrio fischeri and Medicago truncatula-Sinorhizobium meliloti symbioses. FlavoHb expression affects Aspergillus nidulans sexual development and mycotoxin production, and Dictyostelium discoideum development. This family also includes some single-domain goblins (SDgbs).

 4-142 3.95e-05

Vitreoscilla stercoraria hemoglobin and related proteins; single-domain globins; VtHb is homodimeric, and may both transport oxygen to terminal respiratory oxidases, and provide resistance to nitrosative stress. It has medium oxygen affinity and displays cooperative ligand-binding properties. VHb has biotechnological application, its expression in heterologous hosts (bacteria and plants) has improved growth and productivity under microaerobic conditions. Another member of this subfamily Campylobacter jejuni hemoglobin (Cgb) is monomeric, and plays a role in detoxifying NO. Along with a truncated globin Ctb, it is up-regulated by the transcription factor NssR in response to nitrosative stress.
