Enzyme Information
| 2.7.13.3 | 
							 Histidine kinase. 
							based on mapping to UniProt O31671 		
							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.
