Comment |
Requires Mg2+ for activity. The mammalian enzyme is membrane-bound and catalyses the first step in the conjugation of bile acids with amino acids, converting bile acids into their acyl-CoA thioesters. Chenodeoxycholate, deoxycholate, lithocholate and trihydroxycoprostanoate can also act as substrates [7]. The bacterial enzyme is soluble and participates in an anaerobic bile acid 7 alpha-dehydroxylation pathway [5].
