Accepted name: 3α-hydroxy bile acid-CoA-ester 3-dehydrogenase
Reaction: a 3α-hydroxy bile acid CoA ester + NAD+ = a 3-oxo bile acid CoA ester + NADH + H+
Other name(s): baiA1 (gene name); baiA2 (gene name); baiA3 (gene name)
Systematic name: 3α-hydroxy-bile-acid-CoA-ester:NAD+ 3-oxidoreductase
Comments: This bacterial enzyme is involved in the 7-dehydroxylation process associated with bile acid degradation. The enzyme has very little activity with unconjugated bile acid substrates. It has similar activity with choloyl-CoA, chenodeoxycholoyl-CoA, deoxycholoyl-CoA, and lithocholoyl-CoA.
