Protein attributes

Sequence length	196 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

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 By similarity. HAMAP-Rule MF_00444
Catalytic activity	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). HAMAP-Rule MF_00444
Subunit structure	Component of the chloroplastic Clp protease core complex.
Subcellular location	Plastid › chloroplast stroma By similarity.
Sequence similarities	Belongs to the peptidase S14 family.
