Function and Biology Details

Reaction catalysed:
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).
