IUBMB Enzyme Nomenclature


Accepted name: tyrosine-ester sulfotransferase

Reaction: 3'-phosphoadenylyl sulfate + L-tyrosine methyl ester = adenosine 3',5'-bisphosphate + L-tyrosine methyl ester 4-sulfate

Glossary: 3'-phosphoadenylyl sulfate = PAPS

Other names: aryl sulfotransferase IV; L-tyrosine methyl ester sulfotransferase

Systematic name: 3'-phosphoadenylyl-sulfate:L-tyrosine-methyl-ester sulfotransferase

Comments: Phenols and organic hydroxylamines can act as acceptors (cf. EC aryl sulfotransferase).
