beta-trefoil_STI_BbKI-like cd23364
soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in Bauhinia bauhinioides ...
 3-164 1.23e-123

soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in Bauhinia bauhinioides Kunitz-type serine protease inhibitor BbKI and similar proteins; This subfamily includes Bauhinia bauhinioides BbKI, BbCI, Bauhinia rufa BrTI, and similar proteins. BbKI inhibits bovine trypsin, human plasma kallikrein and plasmin, and weakly inhibits bovine chymotrypsin. BbCI inhibits cruzipain, a cysteine proteinase from Trypanosoma cruzi. It also inhibits cathepsin L, a cysteine proteinase with high homology to cruzipain, but not cathepsin B, papain, bromelain, or ficin. BrTI acts as an inhibitor of trypsin and human plasma kallikrein. It does not inhibit chymotrypsin, porcine pancreatic elastase, human neutrophil elastase, coagulation factor Xa, human thrombin, porcine pancreatic kallikrein or plasmin. Members of this subfamily contain an STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

WTI-1 is a Kunitz type protease inhibitor that inhibits bovine trypsin stoichiometrically, but not bovine alpha-chymotrypsin. WCI-3 is a Kunitz-type winged bean chymotrypsin inhibitor (WbCI) that inhibits alpha-chymotrypsin at the molar ratio of 1:2 instead of 1:1, the usual ratio of 1:1 common to other members of the family. ETI is a trypsin inhibitor that shows high homology to other Kunitz trypsin protease inhibitors, but has the unique ability to bind and inhibit tissue plasminogen activator. Members of this subfamily contain an STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in Leucaena leucocephala trypsin inhibitor (LlTI) and similar proteins; LlTI is a Kunitz-type trypsin inhibitor that inhibits trypsin, plasmin, human plasma kallikrein, chymotrypsin, and factor XIIa activity. This subfamily also includes tamarind Kunitz inhibitor (TKI), Enterolobium contortisiliquum trypsin inhibitor (EcTI), Acacia confusa trypsin inhibitor (AcTI), Bauhinia ungulata factor Xa inhibitor BuXI, and Phanera variegata trypsin inhibitor BvTI. TKI is a Kunitz-type dual inhibitor (TKI) of factor Xa (FXa) and trypsin. It shows prolongation of blood coagulation time. EcTI also belongs to the Kunitz family of plant inhibitors, common in plant seeds. It inhibits trypsin, chymotrypsin, plasma kallikrein, plasmin, human neutrophil elastase, and Factor XIIa in the stoichiometric ratio 1:1, but not thrombin, bovine pancreatic elastase, or Factor Xa. It is involved in the inhibition of the invasion of gastric cancer cells through alterations in integrin-dependent cell signaling pathway. AcTI inhibits trypsin and alpha-chymotrypsin stoichiometrically at the molar ratio of 1:1 and 2:1 respectively. BuXI inhibits bovine trypsin and chymotrypsin, and human plasmin, plasma kallikrein, factor XIIa, and factor Xa. BvTI inhibits bovine trypsin and chymotrypsin, and human plasmin, plasma kallikrein and factor XIIa. Members of this subfamily contain an STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 4-162 1.70e-20

soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in the soybean Kunitz trypsin inhibitor (SKTI) subfamily; SKTI is extracted from soybean (Glycine max L.) seeds. It shows inhibition of trypsin and possesses insect resistance and anti-tumor properties. This subfamily includes KTI1-3. KTI1 and KTI2 probably do not possess trypsin inhibitor activity. KTI3, also called trypsin inhibitor A, is responsible for most of the Kunitz trypsin inhibitor activity and protein found in soybean seeds. Members of this subfamily contain a soybean trypsin inhibitor (STI)-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 5-162 4.16e-16

soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in Vitis vinifera miraculin-like protein (VvMLP) and similar proteins; This subfamily includes VvMLP, Synsepalum dulcificum miraculin (SdMIR), and Arabidopsis thaliana Kunitz trypsin inhibitor 5 (AtKTI5, also known as AtKTI2). VvMLP exhibits significant homology to miraculin. However, it exists as a monomer in solution with no detectable taste-modifying activity. It can act as a moderate trypsin inhibitor. SdMIR has the property of modifying a sour taste into a sweet taste. This alteration of taste perception persists for many minutes. AtKTI5 can inhibit both serine proteases and cysteine proteases. It may be involved in the modulation of the proteases that participate in the hydrolysis of dietary proteins in the gut of spider mites. Members of this subfamily contain an STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

TcASP shows homology to the soybean trypsin inhibitor (Kunitz) family of protease inhibitors. MkMLP is closer to miraculin, a taste modifying protein, rather than classical Kunitz family members like soybean Kunitz-type trypsin inhibitor (STI). MkMLP is functionally unstable at higher temperatures. Members of this subfamily contain an STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in class II water-soluble chlorophyll proteins (WSCPs) and similar proteins; There are two kinds of water-soluble chlorophyll (Chl) proteins (WSCPs): Chenopodium-type (Class I, a WSCP from Chenopodium, Atriplex, Polygonum, and Amaranthus species) and Brassica-type (Class II, a WSCP from Brassica, Raphanus, and Lepidium species). Classes I and II WSCPs differ mainly in their photoconvertiblity. Class I WSCPs show a light-induced absorption change, whereas Class II WSCPs do not. This family includes Class II WSCPs. They possess the complete motif of the Kunitz-type proteinase inhibitor but may not inhibit trypsin, whose activity is inhibited strongly by one Kunitz-proteinase inhibitor, the soybean trypsin inhibitor (STI). Members of this subfamily contain a STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

 5-138 4.74e-07

soybean trypsin inhibitor (STI)-like domain, beta-trefoil fold, found in Mucuna pruriens MP-4 and similar proteins; This subfamily includes Mucuna pruriens MP-4, Canavalia lineata subtilisin inhibitor CLSI-II, Cicer arietinum trypsin protein inhibitor 2 (CaTI2), Pisum sativum Kunitz-type trypsin inhibitor-like 1 protein (PIP20-1) and Kunitz-type trypsin inhibitor-like 2 protein (PIP20-2). MP-4 contributes significantly to the snake venom neutralization activity of Mucuna pruriens seeds through an indirect antibody-mediated mechanism and not through direct inhibition of venom proteases. CLSI-II inhibits subtilisin-type microbial serine proteases including proteinase K, subtilisin BPN', subtilisin Carlsberg and subtilisin E in a non-stoichiometric manner. It weakly inhibits Aspergillus oryzae protease and some metalloproteases including pronase E. It does not inhibit trypsin, chymotrypsin, Streptomyces griseus alkaline protease or Achromobacter lyticus lysyl endopeptidase. CLSI-II has a wider inhibitory specificity than CLSI-III. CaTI2 is a Kunitz trypsin inhibitor (KTI) with antifungal effect on Fusarium oxysporum f. sp. ciceris, a fungal pathogen known to cause severe damage to chickpea crop. It may be binding to the trypsin active pocket in a non-substrate like manner. PIP20-1 (also called protease inhibitor from pea 1 or FUC1) and PIP20-2 (also called protease inhibitor from pea 2 or FUC2) may act as protease inhibitors involved in plant defense responses. Members of this subfamily contain an STI-like domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.
