3-dehydrosphinganine reductase
catalyzes the
chemical reaction: The two
substrates of this enzyme are sphinganine and oxidised
nicotinamide adenine dinucleotide phosphate (NADP+). Its
products are 3-ketosphinganine, reduced NADPH, and a
proton. This enzyme belongs to the family of
oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. This enzyme participates in
sphingolipid metabolism. == Tissue distribution ==
