Demethylmacrocin O-methyltransferase

In enzymology, a demethylmacrocin O-methyltransferase (EC 2.1.1.102) is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + demethylmacrocin ${\displaystyle \rightleftharpoons }$ S-adenosyl-L-homocysteine + macrocin

Thus, the two substrates of this enzyme are S-adenosyl methionine and , whereas its two products are S-adenosylhomocysteine and macrocin.

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:demethylmacrocin 2"'-O-methyltransferase. This enzyme is also called demethylmacrocin methyltransferase. This enzyme participates in .
