Enzyme Information
| 2.7.13.3 |
Histidine kinase.
based on mapping to UniProt Q9C5U0
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.
|
| 3.1.3.16 |
Protein-serine/threonine phosphatase.
based on mapping to UniProt Q9C5U0
[a protein]-serine/threonine phosphate + H(2)O = [a protein]- serine/threonine + phosphate.
-!- A group of enzymes removing the serine- or threonine-bound phosphate group from a wide range of phosphoproteins, including a number of enzymes which have been phosphorylated under the action of a kinase (cf. EC 3.1.3.48). -!- The spleen enzyme also acts on phenolic phosphates and phosphamides (cf. EC 3.9.1.1).
