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}.
