Pyrogallol hydroxytransferase (EC 5.4.4.9) is an enzyme that catalyzes a chemical reaction that converts pyrogallol to phloroglucinol by formation of the intermediate 1,2,3,5-tetrahydroxybenzene.[1]
The enzyme isolated from the bacterium Pelobacter acidigallici contains molybdenum but the hydroxyl group which is initially added to pyrogallol does not come from water. Instead, some sulfoxides and aromatic N-oxides can provide these groups.[2][3]
Nomenclature
[edit]This enzyme belongs to the family of oxidoreductases. The systematic name of this enzyme class is 1,2,3,5-tetrahydroxybenzene:1,2,3-trihydroxybenzene hydroxytransferase. Other names in common use include 1,2,3,5-tetrahydroxybenzene hydroxyltransferase, 1,2,3,5-tetrahydroxybenzene:pyrogallol transhydroxylase, 1,2,3,5-tetrahydroxybenzene-pyrogallol hydroxyltransferase (transhydroxylase), pyrogallol hydroxyltransferase, 1,2,3,5-tetrahydroxybenzene:1,2,3-trihydroxybenzene hydroxyltransferase.[4]
