Enzyme Information

2.7.1.73
Inosine kinase.
based on mapping to UniProt Q9HJT3
ATP + inosine = ADP + IMP.
2.7.1.-
Phosphotransferases with an alcohol group as acceptor.
based on mapping to UniProt Q9HJT3
2.7.1.213
Cytidine kinase.
based on mapping to UniProt Q9HJT3
ATP + cytidine = ADP + CMP.
-!- The enzyme, characterized from the archaeon Thermococcus kodakarensis, participates in a pathway for nucleoside degradation. -!- The enzyme can also act on deoxycytidine and uridine, but unlike EC 2.7.1.48 it is most active with cytidine.
2.7.1.20
Adenosine kinase.
based on mapping to UniProt Q9HJT3
ATP + adenosine = ADP + AMP.
-!- 2-aminoadenosine can also act as acceptor.
