Phenol 2-monooxygenase, stimulatory component DmpM

UniProtKB accession:  P19731

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Part of a multicomponent enzyme which catalyzes the degradation of phenol and some of its methylated derivatives (PubMed:2254259). DmpM is a regulatory subunit that stimulates the phenol hydroxylase activity of the complex (PubMed:10451366, PubMed:12186554). The steady-state rate of phenol hydroxylase turnover is dependent on the DmpM concentration, with a maximum observed rate at about 1.5 DmpM per oxygenase monomer. Higher concentrations of DmpM inhibit phenol hydroxylase activity (PubMed:12186554). May act by altering the redox potential of the oxygenase (PubMed:12186554). Required for growth on phenol and for in vitro phenol hydroxylase activity (PubMed:2254258, PubMed:2254259).
