In enzymology, a tetrahydroxynaphthalene reductase (EC 1.1.1.252) is an enzyme that catalyzes the chemical reaction
- scytalone + NADP+ [math]\displaystyle{ \rightleftharpoons }[/math] 1,3,6,8-tetrahydroxynaphthalene + NADPH + H+
Thus, the two substrates of this enzyme are scytalone and NADP+, whereas its 3 products are 1,3,6,8-tetrahydroxynaphthalene, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is scytalone:NADP+ Delta5-oxidoreductase.
Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1DOH, 1G0N, and 1G0O.
