1.1.1.218 additional information the rabbit enzyme shows high coenzyme preference for NAD+ over NADP+. Also in the reverse reaction, the enzymes reduces several alpha-dicarbonyl compounds including S-camphorquinone using NADH as the coenzyme, exhibiting low Km values of 0.004-0.006 mM. The reductase activity of the enzyme determined with NADPH as the coenzyme is less than 40% of their NADH-linked activity 739953 1.1.1.218 NAD(P)+ - 667890 1.1.1.218 NAD(P)+ NAD+ preferred cofactor 286286 1.1.1.218 NAD(P)+ utilized both with nearly equal efficiency 286281, 286282 1.1.1.218 NAD(P)H enzyme specific for the proR hydrogen of NADPH 286289 1.1.1.218 NAD(P)H NADPH: 2.7 times as effective as NADH 286282 1.1.1.218 NAD+ - 739953 1.1.1.218 NAD+ NADP+: only about one-tenth of activity with NAD+ 286287 1.1.1.218 NAD+ with NADP+ enzyme activity less than 5% those found with NAD+ 286288 1.1.1.218 NADP+ the Pseudomonas enzyme acts only with NADP+ 286283, 286284
