Scytalone dehydratase (SD) catalySes the dehydrations of scytalone and vermelone in the fungal melanin biosynthetic pathway. It was first identified in a phytopathogenic fungus, Magnaporthe grisea (Rice blast fungus), which causes rice blast disease. Scytalone dehydratase is a molecular target of inhibitor design efforts aimed at protecting rice plants from fungal disease [PMID:9922139, PMID:14716498].
