CC -!- FUNCTION: Part of a multicomponent enzyme which catalyzes the
CC degradation of phenol and some of its methylated derivatives
CC (PubMed:2254259). DmpL, DmpN and DmpO form the oxygenase component of
CC the complex (PubMed:12186554). Required for growth on phenol and for in
CC vitro phenol hydroxylase activity (PubMed:2254258, PubMed:2254259).
CC {ECO:0000269|PubMed:12186554, ECO:0000269|PubMed:2254258,
CC ECO:0000269|PubMed:2254259}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + NADH + O2 + phenol = catechol + H2O + NAD(+);
CC Xref=Rhea:RHEA:57952, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15379, ChEBI:CHEBI:15882, ChEBI:CHEBI:18135,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.14.13.244;
CC Evidence={ECO:0000269|PubMed:2254259};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:57953;
CC Evidence={ECO:0000269|PubMed:2254259};
CC -!- ACTIVITY REGULATION: Requires DmpM for efficient turnover. The activity
CC of DmpLNO oxygenase is inhibited by dithiothreitol (DTT) by a mechanism
CC apparently involving H(2)O(2) generation.
CC {ECO:0000269|PubMed:12186554}.
CC -!- PATHWAY: Aromatic compound metabolism; phenol degradation.
CC {ECO:0000269|PubMed:2254258}.
CC -!- SUBUNIT: The multicomponent enzyme phenol hydroxylase is formed by DmpL
CC (P1 component), DmpM (P2 component), DmpN (P3 component), DmpO (P4
CC component) and DmpP (P5 component) (PubMed:2254259). The oxygenase
CC component is a dimer composed of three subunits, DmpL, DmpN and DmpO
CC (DmpLNO) (PubMed:12186554). DmpL interacts with the auxiliary protein
CC DmpK (P0 component) (PubMed:8995386). {ECO:0000269|PubMed:12186554,
CC ECO:0000269|PubMed:2254259, ECO:0000269|PubMed:8995386}.
CC -!- DISRUPTION PHENOTYPE: Cells lacking this gene cannot grow on phenol.
CC {ECO:0000269|PubMed:2254258}.
CC -!- SIMILARITY: Belongs to the TmoE/XamoE family. {ECO:0000305}.
