Protein attributes

Sequence length	119 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Predicted.

General annotation (Comments)

Function	Catabolizes phenol, and some of its methylated derivatives. P4 is required for growth on phenol, and for in vitro phenol hydroxylase activity.
Catalytic activity	Phenol + NADPH + O2 = catechol + NADP+ + H2O.
Cofactor	FAD. Fe2+.
Pathway	Aromatic compound metabolism; phenol degradation.
Subunit structure	The multicomponent enzyme phenol hydroxylase is formed by P0, P1, P2, P3, P4 and P5 polypeptides.
