CC -!- FUNCTION: Protease subunit of a proteasome-like degradation complex
CC believed to be a general protein degrading machinery.
CC {ECO:0000255|HAMAP-Rule:MF_00248}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP-dependent cleavage of peptide bonds with broad
CC specificity.; EC=3.4.25.2; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00248};
CC -!- ACTIVITY REGULATION: Allosterically activated by HslU binding.
CC {ECO:0000255|HAMAP-Rule:MF_00248}.
CC -!- SUBUNIT: A double ring-shaped homohexamer of HslV is capped on each
CC side by a ring-shaped HslU homohexamer. The assembly of the HslU/HslV
CC complex is dependent on binding of ATP. {ECO:0000255|HAMAP-
CC Rule:MF_00248}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00248}.
CC -!- SIMILARITY: Belongs to the peptidase T1B family. HslV subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00248}.
