Phenylalanine ammonia lyase (PAL)
Short Description:
About Phenylalanine ammonia lyase
ES-PAL: A class of enzymes that catalyze the direct deamination of L-phenylalanine to trans- cinnamic acid. Syncozymes developed 10 items of phenylalanine ammonia lyase (numbered ES-PAL-101~ES-PAL-110), which can be used in deamination or reverse reaction of phenylalanine and its derivatives.

| Enzyme Powder | ES-PAL-101~ ES-PAL-110 | a set of 10 L-phenylalanine ammonia-lyase, 50 mg each 10 items * 50mg / item, or other quantity |
★ 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 enzyme.
➢ Each kind of ES-PAL corresponding to various optimum reaction conditions, which could be studied individually.
➢ The ES-PAL should be added last into reaction system to maintain the activity.
