Enantiomeric isolated enzyme approach

Whilst the whole-cell approach has proved invaluable, the associated problems of overmetabolism and side reactions can be encountered. Another way to counter the problems of high cost in using isolated BVMOs is to use an NADH dependent enzyme, as NADH retails at approximately one tenth of the cost of NADPH. The Type 2 DKCMOs from Pseudomonas putida ATCC 17453 (= NCIMB 10007) are NADH dependent, and Grogan et al. were successftd in applying a complement of these enzymes, termed MOl, to the transformation of bicyclo[3.2.0]hept-2-en-6-one, to yield another enantiodivergent mix of lactones enantiomeric to those obtained...
