ID 2.1.1.239 DE L-olivosyl-oleandolide 3-O-methyltransferase. CA L-olivosyl-oleandolide + S-adenosyl-L-methionine = H(+) + L-oleandrosyl- CA oleandolide + S-adenosyl-L-homocysteine. CC -!- The enzyme is involved in the biosynthesis of the macrolide CC antibiotic oleandomycin in Streptomyces antibioticus. CC -!- It can also act on other monoglycosylated macrolactones, including CC L-rhamnosyl-erythronolide B and L-mycarosyl-erythronolide B. DR O87833, OLEY_STRAT ; //
