CATH Classification

Domain Context

CATH Clusters

Superfamily P-loop containing nucleotide triphosphate hydrolases
Functional Family ATP-dependent protease (Clp chaperone)

Enzyme Information

3.4.21.92
Endopeptidase Clp.
based on mapping to UniProt P0ABH9
Hydrolysis of proteins to small peptides in the presence of ATP and magnesium. Alpha-casein is the usual test substrate. In the absence of ATP, only oligopeptides shorter than five residues are hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec; and Leu-Tyr-Leu-|-Tyr-Trp, in which cleavage of the -Tyr-|-Leu- and -Tyr-|-Trp bonds also occurs).
-!- Belongs to peptidase family S14.
