KEGG   ENZYME: 1.17.99.1Help
Entry
EC 1.17.99.1                Enzyme                                 

Name
4-methylphenol dehydrogenase (hydroxylating);
p-cresol-(acceptor) oxidoreductase (hydroxylating);
p-cresol methylhydroxylase;
4-cresol dehydrogenase (hydroxylating)
Class
Oxidoreductases;
Acting on CH or CH2 groups;
With unknown physiological acceptors
BRITE hierarchy
Sysname
4-methylphenol:acceptor oxidoreductase (methyl-hydroxylating)
Reaction(IUBMB)
4-methylphenol + 2 acceptor + H2O = 4-hydroxybenzaldehyde + 2 reduced acceptor [RN:R07223]
Reaction(KEGG)
Substrate
4-methylphenol [CPD:C01468];
acceptor [CPD:C00028];
H2O [CPD:C00001]
Product
4-hydroxybenzaldehyde [CPD:C00633];
reduced acceptor [CPD:C00030]
Comment
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.
