Sysname
S-adenosyl-L-methionine:macrocin 3'''-O-methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + macrocin = S-adenosyl-L-homocysteine + tylosin [RN:R02858]
Reaction(KEGG)
R02858
Substrate
S-adenosyl-L-methionine [CPD:C00019];
macrocin [CPD:C00744]
Product
S-adenosyl-L-homocysteine [CPD:C00021];
tylosin [CPD:C01457]
Comment
Requires Mg2+, Mn2+ or Co2+. The 3-hydroxy group of the 2-O-methyl-6-deoxy-D-allose moiety in the macrolide antibiotic macrosin acts as methyl acceptor, generating tylosin, another macrolide antibiotic. Isolated from the bacterium Streptomyces fradiae. Not identical with EC 2.1.1.102, demethylmacrocin O-methyltransferase.
