OX NCBI_TaxID=4673 {ECO:0000313|EMBL:QQP00931.1}; RN [1] {ECO:0000313|EMBL:QQP00931.1} RP NUCLEOTIDE SEQUENCE. RA Lim S.-Y., Jang J.-H., Jung H.-K., Cho H.-W.; RL Submitted (AUG-2020) to the EMBL/GenBank/DDBJ databases. 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: 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; Evidence={ECO:0000256|ARBA:ARBA00034021, CC ECO:0000256|HAMAP-Rule:MF_00444, ECO:0000256|PROSITE- CC ProRule:PRU10086}; CC -!- SUBUNIT: Component of the chloroplastic Clp protease core complex. CC {ECO:0000256|ARBA:ARBA00011607, ECO:0000256|HAMAP-Rule:MF_00444}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma {ECO:0000256|HAMAP- CC Rule:MF_00444}. CC -!- SIMILARITY: Belongs to the peptidase S14 family. CC {ECO:0000256|ARBA:ARBA00007039, ECO:0000256|HAMAP-Rule:MF_00444, CC ECO:0000256|RuleBase:RU003567}.
