O-acetyl-L-homoserine + methanethiol = L-methionine + acetate + H(+)
(6S)-5-methyl-5,6,7,8-tetrahydrofolate + L-homocysteine = (6S)-5,6,7,8-tetrahydrofolate + L-methionine
L-methionine = D-methionine
reduced [flavodoxin] + a menaquinone + 2 S-adenosyl-L-methionine = an 8-methylmenaquinone + oxidized [flavodoxin] + 5'-deoxyadenosine + L-methionine + S-adenosyl-L-homocysteine + 3 H(+)
