an expression vector, pWKLQ, which contains the full length 3-quinuclidinone reductase gene is constructed. Using Escherichia coli cells coexpressing the 3-quinuclidinone reductase and glucose dehydrogenase (cofactor regeneration enzyme) genes, 618 mM 3-quinuclidinone is almost stiochiometrically converted to (R)-3-quinuclidinol with an >99.9% enantiomeric excess within 21 h of reaction

the enzyme can be used for synthesis of optically pure 3-quinuclidinol. Optically pure 3-quinuclidinol is an important intermediate for the synthesis of various anticholinergic drugs. (R)-3-Quinuclidinol is used to synthesize muscarinic M1 or M3 receptor antagonists such as talsaclidine, revatropate, and solifenacin
