Aryl sulfotransferase

Jump to: navigation, search

In enzymology, an aryl sulfotransferase (EC 2.8.2.1) is an enzyme that catalyzes the chemical reaction

3'-phosphoadenylyl sulfate + a phenol adenosine 3',5'-bisphosphate + an aryl sulfate

Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and phenol, whereas its two products are adenosine 3',5'-bisphosphate and aryl 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:phenol sulfotransferase. Other names in common use include phenol sulfotransferase, sulfokinase, 1-naphthol phenol sulfotransferase, 2-naphtholsulfotransferase, 4-nitrocatechol sulfokinase, arylsulfotransferase, dopamine sulfotransferase, p-nitrophenol sulfotransferase, phenol sulfokinase, ritodrine sulfotransferase, and PST. This enzyme participates in sulfur metabolism.
