EC 2.8.2.31 Details

show Brenda entry

EC number

2.8.2.31

Accepted name

petromyzonol sulfotransferase

Reaction

3′-phosphoadenylyl sulfate + 5α-cholan-3α,7α,12α,24-tetrol = adenosine 3′,5′-bisphosphate + 5α-cholan-3α,7α,12α-triol 24-sulfate

Other name(s)

PZ-SULT, 3′-phosphoadenylyl-sulfate:5α-cholan-3α,7α,12α,24-tetrol sulfotransferase

Systematic name

3′-phosphoadenylyl-sulfate:5α-cholan-3α,7α,12α,24-tetrol sulfonotransferase

Comment

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.
