In enzymology, a steroid sulfotransferase (EC 2.8.2.15) is an enzyme that catalyzes the chemical reaction
- 3'-phosphoadenylyl sulfate + a phenolic steroid adenosine 3',5'-bisphosphate + steroid O-sulfate
Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and phenolic steroid, whereas its two products are adenosine 3',5'-bisphosphate and steroid O-sulfate.
This enzyme belongs to the family of transferases, specifically the sulfotransferases, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphoadenylyl-sulfate:phenolic-steroid sulfotransferase. This enzyme is also called steroid alcohol sulfotransferase. This enzyme participates in androgen and estrogen metabolism.
