CC -!- FUNCTION: Methyltransferase required for the conversion of 2-
CC polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3-methyl-
CC 6-methoxy-1,4-benzoquinol (DMQH2). {ECO:0000256|HAMAP-Rule:MF_03191}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2-methoxy-6-all-trans-polyprenyl-1,4-benzoquinol + S-
CC adenosyl-L-methionine = a 6-methoxy-3-methyl-2-all-trans-polyprenyl-
CC 1,4-benzoquinol + H(+) + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:28286, Rhea:RHEA-COMP:10858, Rhea:RHEA-COMP:10859,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:84166, ChEBI:CHEBI:84167; EC=2.1.1.201;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03191};
CC -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_03191}.
CC -!- SUBUNIT: Component of a multi-subunit COQ enzyme complex, composed of
CC at least COQ3, COQ4, COQ5, COQ6, COQ7 and COQ9. {ECO:0000256|HAMAP-
CC Rule:MF_03191}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_03191}; Peripheral membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_03191}; Matrix side {ECO:0000256|HAMAP-Rule:MF_03191}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. MenG/UbiE family. {ECO:0000256|HAMAP-Rule:MF_03191}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_03191}.
