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}.
