IntEnz Enzyme Nomenclature
EC 1.17.99.1

Names

Accepted name:
4-methylphenol dehydrogenase (hydroxylating)
Other names:
p-cresol methylhydroxylase
p-cresol-(acceptor) oxidoreductase (hydroxylating)
4-cresol dehydrogenase (hydroxylating)
Systematic name:
4-methylphenol:acceptor oxidoreductase (methyl-hydroxylating)

Reaction

Cofactor

Comments:

A flavocytochrome c (FAD). Phenazine methosulfate can act as acceptor. A quinone methide is probably formed as intermediate. The first hydroxylation forms 4-hydroxybenzyl alcohol; a second hydroxylation converts this into 4-hydroxybenzaldehyde.
