CC -!- FUNCTION: ATP-dependent serine protease that mediates the selective
CC degradation of misfolded, unassembled or oxidatively damaged
CC polypeptides as well as certain short-lived regulatory proteins in the
CC mitochondrial matrix. May also have a chaperone function in the
CC assembly of inner membrane protein complexes. Participates in the
CC regulation of mitochondrial gene expression and in the maintenance of
CC the integrity of the mitochondrial genome. Binds to mitochondrial DNA
CC in a site-specific manner. {ECO:0000256|HAMAP-Rule:MF_03120}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of proteins in presence of ATP.; EC=3.4.21.53;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03120};
CC -!- SUBUNIT: Homohexamer or homoheptamer. Organized in a ring with a
CC central cavity. {ECO:0000256|HAMAP-Rule:MF_03120}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000256|ARBA:ARBA00004305, ECO:0000256|HAMAP-Rule:MF_03120}.
CC -!- SIMILARITY: Belongs to the peptidase S16 family. {ECO:0000256|HAMAP-
CC Rule:MF_03120, ECO:0000256|PROSITE-ProRule:PRU01122,
CC ECO:0000256|RuleBase:RU000591}.
