| catalytic Activity | CATALYTIC ACTIVITY: Reaction=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).; EC=3.4.21.92; Evidence={ECO:0000255|HAMAP-Rule:MF_00444}; |
| DNA Binding | |
| EC Number | 3.4.21.92 |
| Enzyme Function | FUNCTION: Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. {ECO:0000255|HAMAP-Rule:MF_00444}. |
