Accepted name:
petromyzonol sulfotransferase
Other name:
Systematic name:
3'-phosphoadenylyl-sulfate:5α-cholan-3α,7α,12α,24-tetrol sulfotransferase



The enzyme from the lamprey Petromyzon marinus can also use the corresponding 3-ketone as a substrate. It is stereoselective (5α-cholane) and regioselective, exhibiting a preference for an hydroxy group at C-24. The enzyme is inactive when allocholic acid, which has a carboxy group at C-24, is used as a substrate.
