A KetoREDuctase (KRED) engineered via directed evolution technologies catalyzed the asymmetric reduction of (E)-methyl 2-(3-(3-(2-(7-chloroquinolin-2-yl)vinyl)phenyl)-3-oxopropyl)benzoate to the corresponding (S)-alcohol, a key intermediate in the synthesis of montelukast sodium (Singulair) Through synergistic efforts in process chemistry, molecular biology, bioinformatics and high throughput screening, a KRED with very high enantioselectivity (>99.9% ee) was developed for an economical and simple process that takes advantage of the physical properties of the substrate and product. The evolved KRED is an efficient and robust enzyme for catalyzing the reaction of in essentially water insoluble substrate (c log P approximate to 7) at a 100 g/L loading in the presence of similar to 70% organic solvents at 45 degrees C. The biocatalytic process currently runs at >200 kg scale.
