Reaction Schemes
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)
Synonyms
clp protease, clpap, clpxp protease, clpc1, clpp1, caseinolytic protease, clpp protease, clpp2, clpp1p2, atp-dependent clp protease, more
