Catalyzes the azurin dependent hydroxylation of the methyl group of 4-methylphenol to form 4-hydroxybenzaldehyde. 4-methylphenol + H2O + 4 oxidized [azurin] = 4-hydroxybenzaldehyde + 4 H(+) + 4 reduced [azurin] Binds 1 FAD covalently per subunit. Aromatic compound metabolism; p-cresol degradation. Tetramer of two cytochrome subunits and two flavoprotein subunits.
