Esterase&Lipase (PLE&CALB)
There are 26 kinds of PLE enzyme products (Number as ES-PLE-101～ES-PLE-126) developed by SyncoZymes. ES-PLE can be used for the hydrolysis of aliphatic and ester compounds, or regioselective and stereoselective resolution to synthesize chiral acids and their derivatives.
Catalytic reaction type:
★ High substrate specificity.
★ Strong chiral selectivity.
★ High conversion.
★ Less by-products.
★ Mild reaction conditions.
★ Environmentally friendly.
➢ Normally, the reaction system should include substrate, buffer solution and the ES-PLE. The esterification of some ES-PLEs is carried out in the organic phase.
➢ All kinds of ES-PLEs corresponding to various optimum reaction conditions should be studied individually.
