Protein attributes

Sequence length457 AA.
Sequence statusComplete.
Protein existenceInferred 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.
