| UniProt code: P43773. |
|
||
| Organism: | |
Haemophilus influenzae (strain ATCC 51907 / DSM 11121 / KW20 / Rd). |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Pasteurellales; Pasteurellaceae; Haemophilus. |

| Function: | |
ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis. |
|
||
| Subunit: | |
A double ring-shaped homohexamer of HslV is capped on each side by a ring-shaped HslU homohexamer. The assembly of the HslU/HslV complex is dependent on binding of ATP. {ECO:0000269|PubMed:11106733, ECO:0000269|PubMed:11468391, ECO:0000269|PubMed:12823960}. |
| Subcellular location: | |
Cytoplasm {ECO:0000250}. |
| Similarity: | |
Belongs to the ClpX chaperone family. HslU subfamily. {ECO:0000305}. |
