DE   menaquinone C(8)-methyltransferase.
CA   (1) reduced [flavodoxin] + a menaquinone + 2 S-adenosyl-L-methionine =
CA   an 8-methylmenaquinone + oxidized [flavodoxin] + 5'-deoxyadenosine +
CA   L-methionine + S-adenosyl-L-homocysteine + 3 H(+).
CA   (2) a 2-demethylmenaquinone + reduced [flavodoxin] + 2 S-adenosyl-L-
CA   methionine = a 2-demethyl-8-methylmenaquinone + oxidized [flavodoxin] +
CA   5'-deoxyadenosine + L-methionine + S-adenosyl-L-homocysteine + 3 H(+).
CC   -!- The enzyme, found in a wide range of bacteria and archaea, is a
CC       radical SAM (AdoMet) enzyme that utilizes two molecules of
CC       S-adenosyl-L-methionine, one as the methyl group donor, and one for
CC       the creation of a 5'-deoxyadenosine radical that drives the reaction
CC       forward.
