>PF00280 potato_inhibit: Potato inhibitor I family; InterPro: IPR000864 Peptide proteinase inhibitors can be found as single domain proteins or as single or multiple domains within proteins; these are referred to as either simple or compound inhibitors, respectively
In many cases they are synthesised as part of a larger precursor protein, either as a prepropeptide or as an N-terminal domain associated with an inactive peptidase or zymogen. This domain prevents access of the substrate to the active site. Removal of the N-terminal inhibitor domain either by interaction with a second peptidase or by autocatalytic cleavage activates the zymogen. Other inhibitors interact direct with proteinases using a simple noncovalent lock and key mechanism; while yet others use a conformational change-based trapping mechanism that depends on their structural and thermodynamic properties. This family of proteinase inhibitors belong to MEROPS inhibitor family I13, clan IG. They inhibit peptidases of the S1 (IPR001254 from INTERPRO) and S8 (IPR000209 from INTERPRO) families []. Potato inhibitor type I sequences are not solely restricted to potatoes but are found in other plant species for example: barley endosperm chymotrypsin inhibitor [], and pumpkin trypsin inhibitor. Exceptions are found in leech's, e.g.Hirudo medicinalis (Medicinal leech), but not other metazoa []. In general, the proteins have retained a specificity towards chymotrypsin-like and elastase-like proteases []. Structurally these inhibitors are small (60 to 90 residues) and in contrast with other families of protease inhibitors, they lack disulphide bonds. The inhibitor is a wedge-shaped molecule, its pointed edge formed by the protease-binding loop, which contains the scissile bond. The loop binds tightly to the protease active site, subsequent cleavage of the scissile bond causing inhibition of the enzyme []. The inhibitors (designated type I and II) are synthesised in potato tubers, increasing in concentration as the tuber develops. Synthesis of the inhibitors throughout the plant is also induced by leaf damage; this systemic response being triggered by the release of a putative plant hormone []. Examples found in the bacteria and archaea are probable false positives.; GO: 0004867 serine-type endopeptidase inhibitor activity, 0009611 response to wounding; PDB: 1TEC_I 1SBN_I 1ACB_I 1EGP_A 3TEC_I 2SEC_I 1EGL_A 2TEC_I 1SIB_I 1MEE_I ....
>PF11720 Inhibitor_I78: Peptidase inhibitor I78 family; InterPro: IPR021719 This family includes Aspergillus elastase inhibitor and belongs to MEROPS peptidase inhibitor family I78
>PF03793 PASTA: PASTA domain; InterPro: IPR005543 The PASTA domain is found at the C-termini of several Penicillin-binding proteins (PBP) and bacterial serine/threonine kinases
It binds the beta-lactam stem, which implicates it in sensing D-alanyl-D-alanine - the PBP transpeptidase substrate. In PknB of Mycobacterium tuberculosis (P71584 from SWISSPROT), all of the extracellular portion is predicted to be made up of four PASTA domains, which strongly suggests that it is a signal-binding sensor domain. The domain has also been found in proteins involved in cell wall biosynthesis, where it is implicated in localizing the biosynthesis complex to unlinked peptidoglycan. PASTA is a small globular fold consisting of 3 beta-sheets and an alpha-helix, with a loop region of variable length between the first and second beta-strands. The name PASTA is derived from PBP and Serine/Threonine kinase Associated domain [].; GO: 0008658 penicillin binding; PDB: 2ZC3_C 1QME_A 1RP5_B 2Z2M_C 2Z2L_F 2ZC4_C 1QMF_A 3M9G_A 3PY9_A 1K25_B ....
