Mycinamicin III 3''-O-methyltransferase

 Mycinamicin III 3-O-methyltransferase  (, MycF) is an enzyme with systematic name  S-adenosyl-L-methionine:mycinamicin III 3-O-methyltransferase . This enzyme catalyses the following chemical reaction


 * S-adenosyl-L-methionine + mycinamicin III $$\rightleftharpoons$$ S-adenosyl-L-homocysteine + mycinamicin IV

The enzyme is involved in the biosynthesis of mycinamicin macrolide antibiotics.
