Enzyme Information

2.7.13.3

Histidine kinase.

based on mapping to UniProt P52687

ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.

-!- This entry has been included to accommodate those protein-histidine kinases for which the phosphorylation site has not been established (i.e. either the pros- or tele-nitrogen of histidine). -!- A number of histones can act as acceptor.
