IUBMB Enzyme Nomenclature


Accepted name: steroid sulfotransferase

Reaction: 3'-phosphoadenylyl sulfate + a phenolic steroid = adenosine 3',5'-bisphosphate + steroid O-sulfate

Glossary: 3'-phosphoadenylyl sulfate = PAPS

Other names: steroid alcohol sulfotransferase; 3'-phosphoadenylyl-sulfate:phenolic-steroid sulfotransferase

Systematic name: 3'-phosphoadenylyl-sulfate:phenolic-steroid sulfonotransferase

Comments: Broad specificity resembling EC alcohol sulfotransferase, but also acts on estrone.
