Application

EC Number Application Comment Organism
1.1.1.B52 pharmacology stereospecific production of (R)-3-quinuclidinol, an important chiral building block for the synthesis of various pharmaceuticals. The 3-quinuclidinone reductase and Leifsonia sp. alcohol dehydrogenase genes are efficiently expressed in Escherichia coli cells. A number of constructed Echerichia coli biocatalysts (intact or immobilized) are applied to the resting cell reaction and optimized. Under the optimized conditions, (R)-(-)-3-quinuclidinolis synthesized from 3-quinuclidinone (15% w/v, 939 mM) giving a conversion yield of 100% for the immobilized enzyme. The optical purity of the (R)-(-)-3-quinuclidinol produced by the enzymatic reactions is above 99.9% Microbacterium luteolum
