In enzymology, a macrocin O-methyltransferase (EC 2.1.1.101) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are S-adenosyl methionine and macrocin, whereas its two products are S-adenosylhomocysteine and tylosin.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases.
The systematic name of this enzyme class is S-adenosyl-L-methionine:macrocin 3"'-O-methyltransferase.
Other names in common use include macrocin methyltransferase, and S-adenosyl-L-methionine-macrocin O-methyltransferase.
