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 1.1.1.239 additional information the rabbit enzymes show high coenzyme preference for NAD+ over NADP+.
