1.1.1.358 | 2-dehydropantolactone + NADPH + H+ |
recombinant CorCPR exhibited a high catalytic activity for the synthesis of (R)-pantolactone ((R)-PL) from 2-dehydropantolactone (KPL). The activity assay is performed using purified CorCPR and crude recombinant GDH in a single batch reaction. GDH is used to complete the enzyme-coupled NADPH regeneration system. CPR-01 form Candida orthopsilosis Co 90-125 exhibits excellent enantioselectivity (enantiomeric excess of over 99%). CorCPR exhibits the highest activity and stereoselectivity toward KPL |

enzyme CduCPR shows high catalytic activity and stereoselectivity using 2-dehydropantolactone (KPL) as the substrate. In a continuous feeding reaction, 200 mM ketopantolactone is reduced to (R)-pantolactone with 98% conversion and 99% enantiomeric excess within 2.0 h by the purified recombinant enzyme |
