Sysname
CMP-N-acetylneuraminate,ferrocytochrome-b5:oxygen oxidoreductase (N-acetyl-hydroxylating)
Reaction(IUBMB)
CMP-N-acetylneuraminate + 2 ferrocytochrome b5 + O2 + 2 H+ = CMP-N-glycoloylneuraminate + 2 ferricytochrome b5 + H2O [RN:R01115]
Reaction(KEGG)
R01115;
(other) R01803
Substrate
CMP-N-acetylneuraminate [CPD:C00128];
ferrocytochrome b5 [CPD:C00999];
O2 [CPD:C00007];
H+ [CPD:C00080]
Product
CMP-N-glycoloylneuraminate [CPD:C03691];
ferricytochrome b5 [CPD:C00996];
H2O [CPD:C00001]
Comment
This enzyme contains both a Rieske-type [2Fe-2S] cluster and a second iron site. The ferricytochrome b5 produced is reduced by NADH and cytochrome-b5 reductase (EC 1.6.2.2). The enzyme can be activated by Fe2+ or Fe3+.
History
