Bile-acid 7alpha-dehydroxylase (EC 1.17.99.5, cholate 7alpha-dehydroxylase, 7alpha-dehydroxylase, bile acid 7-dehydroxylase) was thought to be an enzyme with systematic name deoxycholate:NAD+ oxidoreductase.[1][2][3][4]
However, it was later shown that the dehydroxylation is carried out by seven different enzymes, catalyzing a total of 8 reactions. The enzymes are EC 6.2.1.7, EC 1.1.1.395, EC 1.3.1.115, EC 2.8.3.25, EC 4.2.1.106, EC 1.3.1.114, and EC 1.1.1.52.
