ENZYME entry: EC 2.1.1.303

Accepted Name
2,7-dihydroxy-5-methyl-1-naphthoate 7-O-methyltransferase
Alternative Name(s)
neocarzinostatin O-methyltransferase
Reaction catalysed
2,7-dihydroxy-5-methyl-1-naphthoate + S-adenosyl-L-methionine <=> 2-hydroxy-7-methoxy-5-methyl-1-naphthoate + H(+) + S-adenosyl-L-homocysteine
Comment(s)
  • 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.
