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. |
