CC   -!- FUNCTION: Cleaves peptides in various proteins in a process that
CC       requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a
CC       major role in the degradation of misfolded proteins (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of proteins to small peptides in the presence of
CC         ATP and magnesium. alpha-casein is the usual test substrate. In the
CC         absence of ATP, only oligopeptides shorter than five residues are
CC         hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec, and Leu-Tyr-Leu-|-Tyr-
CC         Trp, in which cleavage of the -Tyr-|-Leu- and -Tyr-|-Trp bonds also
CC         occurs).; EC=3.4.21.92;
CC   -!- SUBUNIT: Component of the plastid Clp protease core complex.
CC   -!- SUBCELLULAR LOCATION: Plastid.
CC   -!- SIMILARITY: Belongs to the peptidase S14 family. {ECO:0000305}.
CC   -!- CAUTION: Young tissue from this organism is photosynthetic and contains
CC       some thylakoids, although the photosynthetic activity does not exceed
CC       the light compensation point. {ECO:0000305}.
