RC STRAIN=R23275 {ECO:0000313|EMBL:OLO74469.1, RC ECO:0000313|Proteomes:UP000186219}; RA Mughal S.R., Do T., Gilbert S.C., Witherden E.A., Didelot X., RA Beighton D.; RT "Genomic comparison of strains in the 'Actinomyces naeslundii' RT group."; RL Submitted (DEC-2016) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Methyltransferase required for the conversion of CC demethylmenaquinol (DMKH2) to menaquinol (MKH2). CC {ECO:0000256|HAMAP-Rule:MF_01813}. CC -!- CATALYTIC ACTIVITY: A demethylmenaquinol + S-adenosyl-L-methionine CC = a menaquinol + S-adenosyl-L-homocysteine. {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 CC methyltransferase superfamily. MenG/UbiE family. CC {ECO:0000256|HAMAP-Rule:MF_01813, ECO:0000256|SAAS:SAAS00652209}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:OLO74469.1}.
