| Reaction(IUBMB) |
Hydrolysis of proteins to small peptides in the presence of ATP and Mg2+. alpha-Casein is the usual test substrate. In the absence of ATP, only oligopeptides shorter than five residues are hydrolysed (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)

| Comment |
An enzyme from bacteria that contains subunits of two types, ClpP, with peptidase activity, and ClpA, with ATPase activity. The ClpAP complex, which displays ATP-dependent endopeptidase activity, has the composition (ClpP14ClpA6)2 [4]. ClpP is the type example of peptidase family S14
