Reaction: S-adenosyl-L-methionine + O-demethylpuromycin = S-adenosyl-L-homocysteine + puromycin
Other name(s): O-demethylpuromycin methyltransferase
Systematic name: S-adenosyl-L-methionine:O-demethylpuromycin O-methyltransferase
Comments: Puromycin is the antibiotic derived from N6-dimethyladenosine by replacing the 3'-hydroxy group with an amino group and acylating this with 4-O-methyltyrosine.
