Demethylmenaquinone methyltransferase (EC 2.1.1.163, S-adenosyl-L-methionine-DMK methyltransferase, demethylmenaquinone C-methylase, 2-heptaprenyl-1,4-naphthoquinone methyltransferase, 2-demethylmenaquinone methyltransferase, S-adenosyl-L-methionine:2-demethylmenaquinone methyltransferase) is an enzyme with systematic name S-adenosyl-L-methionine:demethylmenaquinone methyltransferase.^[1][2][3][4] This enzyme catalyses the following chemical reaction

demethylmenaquinol + S-adenosyl-L-methionine ${\displaystyle \rightleftharpoons }$ menaquinol + S-adenosyl-L-homocysteine

The enzyme catalyses the last step in menaquinone biosynthesis.
