Шаблон:Short description

Шаблон:Infobox enzyme In enzymology, a (S)-usnate reductase (Шаблон:EC number) 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 + NADШаблон:Sup <math>\rightleftharpoons</math> (S)-usnic acid + NADH + HШаблон:Sup

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 NADШаблон:Sup or NADPШаблон:Sup as acceptor. The systematic name of this enzyme class is reduced-(S)-usnate:NADШаблон:Sup oxidoreductase (ether-bond-forming). This enzyme is also called L-usnic acid dehydrogenase.
