Protein attributes
| Sequence length | 457 AA. |
| Sequence status | Complete. |
| Protein existence | Inferred from homology |
General annotation (Comments)
| Function | This protein is involved in several diverse cellular processes, such as the functioning of acetohydroxyacid synthetase I, in the biosynthesis of isoleucine and valine, the TraJ protein activation activity for tra gene expression in F plasmid, and the synthesis, translocation, or stability of cell envelope proteins. Activates CpxR by phosphorylation By similarity. |
| Catalytic activity | ATP + protein L-histidine = ADP + protein N-phospho-L-histidine. |
| Subcellular location | Cell inner membrane; Multi-pass membrane protein By similarity. |
| Sequence similarities | Contains 1 HAMP domain. Contains 1 histidine kinase domain. |
