CC -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC {ECO:0000256|HAMAP-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}.
