EC 1.1.1.252

Accepted name: tetrahydroxynaphthalene reductase

Reaction: scytalone + NADP+ = 1,3,6,8-tetrahydroxynaphthalene + NADPH + H+

Systematic name: scytalone:NADP+ δ5-oxidoreductase

Comments: Reduces 1,3,6,8-tetrahydroxynaphthalene to scytalone and also reduces 1,3,8-trihydroxynaphthalene to vermelone. Involved with EC 4.2.1.94 scytalone dehydratase in the biosynthesis of melanin in pathogenic fungi.
