IUBMB Enzyme Nomenclature


Accepted name: ω-hydroxy-β-dihydromenaquinone-9 sulfotransferase

Reaction: 3'-phosphoadenylyl sulfate + ω-hydroxy-β-dihydromenaquinone-9 = adenosine 3',5'-bisphosphate + ω-sulfo-β-dihydromenaquinone-9

Glossary: β-dihydromenaquinone-9 = MK-9(II-H2) = 2-methyl-3-[(2E,10E,14E,18E,22E,26E,30E,33E)-3,7,11,15,19,23,27,31,35-nonamethylhexatriaconta-2,10,14,18,22,26,30,33-octaen-1-yl]naphthalene-1,4-dione

Other name(s): stf3 (gene name)

Systematic name: 3'-phosphoadenylyl-sulfate:ω-hydroxy-β-dihydromenaquinone-9 sulfotransferase

Comments: The enzyme catalyses the last step in the production of ω-sulfo-β-dihydromenaquinone-9 by members of the Mycobacterium tuberculosis complex.
