  • PubMed Abstract: 

    The enzyme 1,3,8-trihydroxynaphthalene reductase (THNR) catalyzes an essential reaction in the biosynthesis of melanin, a black pigment crucial for the pathogenesis of the rice blast fungus, Magnaporthe grisea. The enzyme is the biochemical target of several commercially important fungicides which are used to prevent blast disease in rice plants. We have determined the structure of the ternary complex of THNR with bound NADPH and a fungicide, tricyclazole.
