2-215 3.58e-71

Type 1 glutamine amidotransferase (GATase1)-like domain found in peptidase E; Type 1 glutamine amidotransferase (GATase1)-like domain found in peptidase E. This group contains proteins similar to the aspartyl dipeptidases Salmonella typhimurium peptidase E and Xenopus laevis peptidase E. In bacteria peptidase E is believed to play a role in degrading peptides generated by intracellular protein breakdown or imported into the cell as nutrient sources. Peptidase E uniquely hydrolyses only Asp-X dipeptides (where X is any amino acid), and one tripeptide Asp-Gly-Gly. Peptidase E is believed to be a serine peptidase having a Ser-His-Glu catalytic triad which differs from the Cys-His-Glu catalytic triad typical of GATase1 domains by having a Ser in place of the reactive Cys at the nucleophile elbow. Xenopus PepE is developmentally regulated in response to thyroid hormone and, it is thought to play a role in apoptosis during tail reabsorption.

3-215 2.17e-53

Type 1 glutamine amidotransferase (GATase1)-like domain found in peptidase E_like proteins; Type 1 glutamine amidotransferase (GATase1)-like domain found in peptidase E_like proteins. This group contains proteins similar to the aspartyl dipeptidases Salmonella typhimurium peptidase E and Xenopus laevis peptidase E and, extracellular cyanophycinases from Pseudomonas anguilliseptica BI (CphE) and Synechocystis sp. PCC 6803 CphB. In bacteria peptidase E is believed to play a role in degrading peptides generated by intracellular protein breakdown or imported into the cell as nutrient sources. Peptidase E uniquely hydrolyses only Asp-X dipeptides (where X is any amino acid), and one tripeptide Asp-Gly-Gly. Cyanophycinases are intracellular exopeptidases which hydrolyze the polymer cyanophycin (multi L-arginyl-poly-L-aspartic acid) to the dipeptide beta-Asp-Arg. Peptidase E and cyanophycinases are thought to have a Ser-His-Glu catalytic triad which differs from the Cys-His-Glu catalytic triad typical of GATase1 domains by having a Ser in place of the reactive Cys at the nucleophile elbow. Xenopus peptidase E is developmentally regulated in response to thyroid hormone and, it is thought to play a role in apoptosis during tail reabsorption.

This group contains proteins similar to the extracellular cyanophycinases from Pseudomonas anguilliseptica BI (CphE) and Synechocystis sp. PCC 6803 CphB. Cyanophycinases are intracellular exopeptidases which hydrolyze the polymer cyanophycin (multi L-arginyl-poly-L-aspartic acid) to the dipeptide beta-Asp-Arg. Cyanophycinase is believed to be a serine-type exopeptidase having a Ser-His-Glu catalytic triad which differs from the Cys-His-Glu catalytic triad typical of GATase1 domains by having a Ser in place of the reactive Cys at the nucleophile elbow.
