Also recognizes other dihydroxynaphthoate as substrates and catalyzes their regiospecific O-methylation. The carboxylate and its ortho-hydroxy groups of the substrate appear to be crucial for NcsB1 substrate recognition and binding, and O-methylation takes place only at the free hydroxy group of these dihydroxynaphthoic acids.<ref>PMID:18387946</ref> | ||
