CC -!- FUNCTION: FAD-dependent monooxygenase required for the C5-ring
CC hydroxylation during ubiquinone biosynthesis. Catalyzes the
CC hydroxylation of 3-polyprenyl-4-hydroxybenzoic acid to 3-
CC polyprenyl-4,5-dihydroxybenzoic acid. The electrons required for the
CC hydroxylation reaction may be funneled indirectly from NADPH via a
CC ferredoxin/ferredoxin reductase system to COQ6. {ECO:0000256|HAMAP-
CC Rule:MF_03193}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-hydroxy-3-all-trans-hexaprenylbenzoate + 2 H(+) + O2 + 2
CC reduced [2Fe-2S]-[ferredoxin] = 3,4-dihydroxy-5-all-trans-
CC hexaprenylbenzoate + H2O + 2 oxidized [2Fe-2S]-[ferredoxin];
CC Xref=Rhea:RHEA:20361, Rhea:RHEA-COMP:10000, Rhea:RHEA-COMP:10001,

CC ChEBI:CHEBI:84492; Evidence={ECO:0000256|HAMAP-Rule:MF_03193};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|ARBA:ARBA00001974,
CC ECO:0000256|HAMAP-Rule:MF_03193};
CC -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_03193}.
CC -!- SUBUNIT: Component of a multi-subunit COQ enzyme complex.
CC {ECO:0000256|HAMAP-Rule:MF_03193}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_03193}; Peripheral membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_03193}; Matrix side {ECO:0000256|HAMAP-Rule:MF_03193}.
CC -!- SIMILARITY: Belongs to the UbiH/COQ6 family.
CC {ECO:0000256|ARBA:ARBA00005349, ECO:0000256|HAMAP-Rule:MF_03193}.
