2.1.1.351 | S-adenosyl-L-methionine + nocamycin E |
the enzyme is involved in the biosynthesis of nocamycin I and nocamycin II, which both show antimicrobial activity. Compared to nocamycin I, nocamycin E shows inferior antibacterial activity, indicating the methyl group is essential to antibacterial activity |
