(R)-aminopropanol dehydrogenase

Jump to: navigation, search

In enzymology, a (R)-aminopropanol dehydrogenase (EC is an enzyme that catalyzes the chemical reaction

(R)-1-aminopropan-2-ol + NAD+ aminoacetone + NADH + H+

Thus, the two substrates of this enzyme are (R)-1-aminopropan-2-ol and NAD+, whereas its 3 products are aminoacetone, NADH, 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 (R)-1-aminopropan-2-ol:NAD+ oxidoreductase. Other names in common use include L-aminopropanol dehydrogenase, 1-aminopropan-2-ol-NAD+ dehydrogenase, L(+)-1-aminopropan-2-ol:NAD+ oxidoreductase, 1-aminopropan-2-ol-dehydrogenase, DL-1-aminopropan-2-ol: NAD+ dehydrogenase, and L(+)-1-aminopropan-2-ol-NAD+/NADP+ oxidoreductase. This enzyme participates in glycine, serine and threonine metabolism. It requires potassium as a cofactor.
