HR-1 Iron Reducer from the RT Loihi Seamount."; RL Genome Announc. 0:0-0(2018). CC -!- FUNCTION: ATP-dependent serine protease that mediates the CC selective degradation of mutant and abnormal proteins as well as CC certain short-lived regulatory proteins. Required for cellular CC homeostasis and for survival from DNA damage and developmental CC changes induced by stress. Degrades polypeptides processively to CC yield small peptide fragments that are 5 to 10 amino acids long. CC Binds to DNA in a double-stranded, site-specific manner. CC {ECO:0000256|HAMAP-Rule:MF_01973, ECO:0000256|SAAS:SAAS00004329}. CC -!- CATALYTIC ACTIVITY: Hydrolysis of proteins in presence of ATP. CC {ECO:0000256|HAMAP-Rule:MF_01973, ECO:0000256|PIRNR:PIRNR001174, CC ECO:0000256|SAAS:SAAS00338825}. CC -!- SUBUNIT: Homohexamer. Organized in a ring with a central cavity. CC {ECO:0000256|HAMAP-Rule:MF_01973, ECO:0000256|PIRNR:PIRNR001174, CC ECO:0000256|SAAS:SAAS00536021}.
