Reaction: S-adenosyl-L-methionine + N-demethylindolmycin = S-adenosyl-L-homocysteine + indolmycin
Glossary: indolmycin = (5S)-5-[(1R)-1-(indol-3-yl)ethyl]-2-(methylamino)-1,3-oxazolin-4(5H)-one
Other name(s): ind7 (gene name)
Systematic name: S-adenosyl-L-methionine:N-demethylindolmycin N-methyltransferase
Comments: The enzyme, characterized from the bacterium Streptomyces griseus, catalyses the ultimate reaction in the biosynthesis of indolmycin, an antibacterial drug that inhibits the bacterial tryptophantRNA ligase (EC 6.1.1.2).
