CC -!- FUNCTION: Methyltransferase required for the conversion of
CC demethylmenaquinol (DMKH2) to menaquinol (MKH2) and the conversion of
CC 2-polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3-
CC methyl-6-methoxy-1,4-benzoquinol (DMQH2). {ECO:0000255|HAMAP-
CC Rule:MF_01813}.
CC -!- CATALYTIC ACTIVITY:

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01813};
CC -!- PATHWAY: Quinol/quinone metabolism; menaquinone biosynthesis;
CC menaquinol from 1,4-dihydroxy-2-naphthoate: step 2/2.
CC {ECO:0000255|HAMAP-Rule:MF_01813}.
CC -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_01813}.
