Dihydrobunolol dehydrogenase

In enzymology, a dihydrobunolol dehydrogenase (EC 1.1.1.160) is an enzyme that catalyzes the chemical reaction

(+/−)-5-[(tert-butylamino)-2'-hydroxypropoxy]-1,2,3,4-tetrahydro-1- naphthol + NADP⁺ ⇌ (+/−)-5-[(tert-butylamino)-2'-hydroxypropoxy]-3,4-dihydro-1(2H)- naphthalenone + NADPH + H⁺

The three substrates of this enzyme are [[(+/−)-5-[(tert-butylamino)-2'-hydroxypropoxy]-1,2,3,4-tetrahydro-1-naphthol]], and NADP⁺, whereas its 4 products are [[(+/−)-5-[(tert-butylamino)-2'-hydroxypropoxy]-3,4-dihydro-1(2H)-]], naphthalenone, 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 (+/−)-5-[(tert-butylamino)-2'-hydroxypropoxy]-1,2,3,4-tetrahydro-1-n aphthol:NADP⁺ oxidoreductase. This enzyme is also termed bunolol reductase.
