2,7-dihydroxy-5-methyl-1-naphthoate 7-O-methyltransferase.
based on mapping to UniProt Q84HC8
S-adenosyl-L-methionine + 2,7-dihydroxy-5-methyl-1-naphthoate = S-adenosyl-L-homocysteine + 2-hydroxy-7-methoxy-5-methyl-1-naphthoate.
-!- 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 catalyzes 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 catalyzes their regiospecific O-methylation.
