CC -!- FUNCTION: Methyltransferase required for the conversion of
CC demethylmenaquinol (DMKH2) to menaquinol (MKH2). {ECO:0000256|HAMAP-
CC Rule:MF_01813}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2-demethylmenaquinol + S-adenosyl-L-methionine = a
CC menaquinol + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:42640,
CC Rhea:RHEA-COMP:9539, Rhea:RHEA-COMP:9563, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:18151, ChEBI:CHEBI:55437, ChEBI:CHEBI:57856,
CC ChEBI:CHEBI:59789; EC=2.1.1.163; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01813};
CC -!- PATHWAY: Quinol/quinone metabolism; menaquinone biosynthesis;
CC menaquinol from 1,4-dihydroxy-2-naphthoate: step 2/2.
CC {ECO:0000256|HAMAP-Rule:MF_01813}.
CC -!- SIMILARITY: Belongs to the class I-like SAM-binding methyltransferase
CC superfamily. MenG/UbiE family. {ECO:0000256|HAMAP-Rule:MF_01813}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01813}.
