In enzymology, a (S)-usnate reductase (EC 1.1.1.199) is an enzyme that catalyzes the chemical reaction
(6R)-2-acetyl-6-(3-acetyl-2,4,6-trihydroxy-5-methylphenyl)-3-hydroxy-6- methyl-2,4-cyclohexadien-1-one + NAD+
In the reverse direction, (S)-usnate is reduced by NADH with cleavage of the ether bond to form a 7-hydroxy group.
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 reduced-(S)-usnate:NAD+ oxidoreductase (ether-bond-forming). This enzyme is also called L-usnic acid dehydrogenase.
