Biocatalytic cofactor recycled efficiently
Oxidoreductase enzymes are used extensively as biocatalysts for industrial and academic reactions, including pharmaceutical synthesis. But they almost exclusively require expensive cofactors such as NADP+, the oxidized form of the biological cofactor nicotinamide adenine dinucleotide phosphate. The reagent currently costs about $22,000 per mole. Enzymes that can recycle it from its reduced form, NADPH, have drawbacks that have limited their use, such as low activity, unwanted by-product generation, and short lifetimes. Guided by nature, which . . .
