|Comment||This model represents a family of methyltransferases involved in the biosynthesis of menaquinone and ubiqinone. Some members such as the UbiE enzyme from E. coli  are believed to act in both pathways, while others may act in only the menaquinone pathway. These methyltransferases are members of the UbiE/CoQ family of methyltransferases (PF01209) which also contains ubiquinone methyltransferases and other methyltransferases.
Members of this clade include a wide distribution of bacteria and eukaryotes, but no archaea. An outgroup for this clade is provided by the phosphatidylethanolamine methyltransferase (EC 126.96.36.199) from Rhodobacter sphaeroides .
Note that a number of non-orthologous genes which are members of PF03737 have been erroneously annotated as MenG methyltransferases.|
