IntEnz Enzyme Nomenclature
EC 2.8.2.32

Names

Accepted name:
scymnol sulfotransferase
Systematic name:
3'-phosphoadenosine 5'-phosphosulfate:5β-scymnol sulfotransferase

Reaction

Comments:

The enzyme from the shark Heterodontus portusjacksoni is able to sulfate the C27 bile salts 5β-scymnol (the natural bile salt) and 5α-cyprinol (the carp bile salt). Enzyme activity is activated by Mg2+ but inhibited by the product 5β-scymnol sulfate.
