CC   -!- FUNCTION: ATPase subunit of a proteasome-like degradation complex; this
CC       subunit has chaperone activity. The binding of ATP and its subsequent
CC       hydrolysis by HslU are essential for unfolding of protein substrates
CC       subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of
CC       its protein substrates and unfolds these before they are guided to HslV
CC       for hydrolysis. {ECO:0000255|HAMAP-Rule:MF_00249}.
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_00249}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00249}.
CC   -!- SIMILARITY: Belongs to the ClpX chaperone family. HslU subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00249}.
