RL Submitted (APR-2007) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: ATP-dependent serine protease that mediates the selective
CC degradation of mutant and abnormal proteins as well as certain short-
CC lived regulatory proteins. Required for cellular homeostasis and for
CC survival from DNA damage and developmental changes induced by stress.
CC Degrades polypeptides processively to yield small peptide fragments
CC that are 5 to 10 amino acids long. Binds to DNA in a double-stranded,
CC site-specific manner. {ECO:0000255|HAMAP-Rule:MF_01973}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of proteins in presence of ATP.; EC=3.4.21.53;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01973};
CC -!- SUBUNIT: Homohexamer. Organized in a ring with a central cavity.
CC {ECO:0000255|HAMAP-Rule:MF_01973}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01973}.
CC -!- INDUCTION: By heat shock. {ECO:0000255|HAMAP-Rule:MF_01973}.
CC -!- SIMILARITY: Belongs to the peptidase S16 family. {ECO:0000255|HAMAP-
CC Rule:MF_01973}.
