Reaction
S-adenosyl-L-methionine + 2,7-dihydroxy-5-methyl-1-naphthoate = S-adenosyl-L-homocysteine + 2-hydroxy-7-methoxy-5-methyl-1-naphthoate
Systematic Name
S-adenosyl-L-methionine:2,7-dihydroxy-5-methyl-1-naphthoate 7-O-methyltransferase
Function
The enzyme from the bacterium Streptomyces carzinostaticus is involved in the biosynthesis of 2-hydroxy-7-methoxy-5-methyl-1-naphthoate. This compound is part of the enediyne chromophore of the antitumor antibiotic neocarzinostatin. In vivo the enzyme catalyses the regiospecific methylation at the 7-hydroxy group of its native substrate 2,7-dihydroxy-5-methyl-1-naphthoate. In vitro it also recognizes other dihydroxynaphthoic acids and catalyses their regiospecific O-methylation.
Other name
