(±)-ethyl mandelate are important intermediates in the synthesis of numerous pharmaceuticals. Efficient routes for the production of these derivatives are highly desirable. A co-immobilization strategy is developed to overcome the issue of NADPH demand in the short-chain dehydrogenase/reductase (SDR) catalytic process. The SDR from Thermus thermophilus HB8 and the NAD(P)-dependent glucose dehydrogenase (GDH) from Thermoplasma acidophilum DSM 1728 are co-immobilized on silica gel. This dual-system offers an efficient route for the biosynthesis of (+/-)-ethyl mandelate |

azoreductase and glucose 1-dehydrogenase are coupled for both continuous generation of the cofactor NADH and azo dye removal. The results show that 85% maximum relative activity of azoreductase in an integrated enzyme system is obtained at the conditions: 1 U azoreductase: 10 U glucose 1-dehydrogenase, 250 mM glucose, 1.0 mM NAD+ and 150 microM methyl red |

co-immobilization of ketoreductase (KRED) and glucose dehydrogenase (GDH) on highly cross-linked agarose (sepharose) via affnity interaction between His-tagged enzymes (six histidine residues on the N-terminus of the protein) and agarose matrix charged with nickel (Ni2+ ions). Immobilized enzymes are applied in a set of biotransformation reactions in repeated batch flow-reactor mode. Immobilization reduces the requirement for cofactor (NADP+) and allows the use of higher substrate concentration in comparison with free enzymes |

enzymatic reduction of the nicotinamide biomimetic cofactors 1-phenethyl-1,4-dihydropyridine-3-carboxamide using glucose dehydrogenase mutant I192T/V306I provides a regeneration system for artificial cofactors. The I192T/V306I mutant enzyme shows 10fold higher activity with 1-phenethyl-1,4-dihydropyridine-3-carboxamide compared with the wild-type enzyme. Using this engineered variant in combination with an enoate reductase from Thermus scotoductus results in an enzyme-coupled regeneration process for biomimetic cofactor without ribonucleotide or ribonucleotide analogue and full conversion of 10 mM 2-methylbut-2-enal with 1-phenethyl-1,4-dihydropyridine-3-carboxamide as cofactor |

production of tert-butyl (3R,5S)-6-chloro-3,5-dihydroxyhexanoate, an important chiral intermediate for the synthesis of rosuvastatin, using carbonyl reductase coupled with glucose dehydrogenase. A recombinant Escherichia coli strain harboring carbonyl reductase R9M and glucose dehydrogenase is constructed with high carbonyl reduction activity and cofactor regeneration efficiency. The recombinant Escherichia coli cells are applied for the efficient production of tert-butyl (3R,5S)-6-chloro-3,5-dihydroxyhexanoate with a substrate conversion of 98.8%, a yield of 95.6% and an enantiomeric excess of more than 99.0% under 350 g/l of tert-butyl (S)-6-chloro-5-hydroxy-3-oxohexanoate after 12 h reaction. A substrate fed-batch strategy is further employed to increase the substrate concentration to 400 g/l resulting in an enhanced product yield to 98.5% after 12 h reaction in a 1 l bioreactor. Meanwhile, the space-time yield is 1182.3 g/l*day |
