RX PubMed=25270575; DOI=10.1186/s12862-014-0211-2; RA Lemieux C., Otis C., Turmel M.; RT "Chloroplast phylogenomic analysis resolves deep-level relationships RT within the green algal class Trebouxiophyceae."; RL BMC Evol. Biol. 14:211-211(2014). 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. CC {ECO:0000256|HAMAP-Rule:MF_00444}. CC -!- CATALYTIC ACTIVITY: Hydrolysis of proteins to small peptides in CC the presence of ATP and magnesium. Alpha-casein is the usual test CC substrate. In the absence of ATP, only oligopeptides shorter than CC five residues are hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec; CC and Leu-Tyr-Leu-|-Tyr-Trp, in which cleavage of the -Tyr-|- CC Leu- and -Tyr-|-Trp bonds also occurs). {ECO:0000256|HAMAP- CC Rule:MF_00444, ECO:0000256|PROSITE-ProRule:PRU10086, CC ECO:0000256|RuleBase:RU000549}. CC -!- SUBUNIT: Component of the chloroplastic Clp protease core complex. CC {ECO:0000256|HAMAP-Rule:MF_00444}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma CC {ECO:0000256|HAMAP-Rule:MF_00444}. CC -!- SIMILARITY: Belongs to the peptidase S14 family.
