show Brenda entryEC number
1.3.1.115
Accepted name
3-oxocholoyl-CoA 4-desaturase
Reaction
(1) 7α,12α-dihydroxy-3-oxochol-24-oyl-CoA + NAD+ = 7α,12α-dihydroxy-3-oxochol-4-en-24-oyl-CoA + NADH + H+;;(2) 7α-hydroxy-3-oxochol-24-oyl-CoA + NAD+ = 7α-hydroxy-3-oxochol-4-en-24-oyl-CoA + NADH + H+
Other name(s)
baiCD (gene name),
3-oxo-choloyl-CoA dehydrogenase
Systematic name
3-oxocholoyl-CoA Δ4-oxidoreductase
Comment
Contains flavin. The enzyme, characterized from the bacterium Clostridium scindens, participates in the bile acid 7α-dehydroxylation pathway. The enzyme catalyses the stereo-specific oxidation of its substrates and has no activity with the 7β anomers. cf. EC 1.3.1.116, 7β-hydroxy-3-oxochol-24-oyl-CoA 4-desaturase.
