Enzyme Information

2.7.13.3	Histidine kinase. based on mapping to UniProt P0AFB5 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.
3.1.3.-	Phosphoric monoester hydrolases. based on mapping to UniProt P0AFB5
