Factory For Nadh Vitamin B3 - Ketoreductase (KRED) – SyncoZymes

KRED from SyncoZymes: There are 191 kinds of KRED enzyme products (Number as ES-KRED-101~ES-KRED-291) developed by SyncoZymes. SZ-KRED could be widely used in regio- and stereoselective reduction of aldehydes, beta-ketone esters, α-ketone esters and ketones.

Catalytic reaction type:

★ High substrate specificity.
★ Strong chiral selectivity.
★ High conversion efficiency.
★ Less by-products.
★ Mild reaction conditions.
★ Environmentally friendly.

➢ Enzyme screening should be carried out for specific substrates because of the substrate specificity, and get an enzyme that catalyzes the target substrate with best catalytic effect.
➢ Never contact with extreme conditions such as: high temperature, high/low pH and organic solvent with high concentration.
➢ Normally, the reaction system should include substrate, buffer solution, coenzymes( NAD(H) or NADP(H) ), coenzyme regeneration system(e.g. glucose and glucose dehydrogenase).
➢ KRED should be added last into reaction system, after the pH and temperature been adjusted to the reaction condition.
➢ All kinds of KRED have various optimum reaction conditions, so each of them should be further studied individually.
