(+)-(1S,2S)-pseudoephedrine:NAD+ 1-oxoreductase

Reactions

Comments:

The enzyme, characterized from the bacterium Arthrobacter sp. TS-15, acts on a broad range of different aryl-alkyl ketones, such as haloketones, ketoamines, diketones, and ketoesters. It accepts various types of aryl groups including phenyl-, pyridyl-, thienyl-, and furyl-rings, but the presence of an aromatic ring is essential for the activity. In addition, the presence of a functional group on the alkyl chain, such as an amine, a halogen, or a ketone, is also crucial. The enzyme exhibits a strict anti-Prelog enantioselectivity. When acting on diketones, it catalyses the reduction of only the keto group closest to the ring, with no further reduction to the diol. Cf. EC 1.1.1.423.
