Ene reductase (ERED)

Short Description:

About ene reductase

ES-EREDs: Belong to the family of old yellow enzymes that selectively reduce C=C in α, β -unsaturated compounds with electron-absorbing groups. They are widely used in the study of amino acid derivatives, bioactive substances, pharmaceutical intermediates, spices and chiral blocks.

About ene reductase:

ES-EREDs catalyze various substrate types because of wide spectrum of substrates. In general, the C=C of α, β -unsaturated compounds with electron-absorbing groups (including ketone aldehyde, nitro groups, carboxylic acids, esters, anhydride, lactones, imines, etc.) are easily reduced by ES-EREDs, but the unactivated double bonds not.

There are 46 kinds of ERED enzyme products (Number as ES-ERED-101~ES-ERED-146) developed by SyncoZymes.

Catalytic mechanism:

Ene reductase ERED1

Product Information:

Ene reductase ERED2
Enzymes Product Code Specification
Enzyme Powder ES-ERED-101~ ES-ERED-146 a set of 46 Ene Reductases, 50 mg each 46 items * 50mg / item, or other quantity
Screening Kit (SynKit) ES-ERED-4600 a set of 46 Ene Reductases, 50 mg each 46 items * 50mg / item, or other quantity


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

Instructions for use:

➢ Normally, the reaction system should include substrate, buffer solution (optimum reaction pH), coenzymes(NAD(H) or NADP(H) ), coenzyme regeneration system(e.g. glucose and glucose dehydrogenase) and ES-ERED.
➢ All the ES-EREDs can be tested respectively in the reaction system above or with the ERED Screening Kit (SynKit ERED).
➢ All kinds of ES-EREDs corresponding to various optimum reaction conditions should be studied individually.
➢ High concentration Substrate or product with may inhibit ES-ERED’s activity. However, the inhibition can be relieved by batch addition of substrate.

Application Examples:

Example 1(α,β-unsaturated aldehydes or ketones) (1):

Ene reductase ERED3

Example 2(α,β-unsaturated carboxylic acids and their derivatives) (2):

Ene reductase ERED4


Keep 2 years below -20℃.


Never contact with extreme conditions such as: high temperature, high/low pH and high concentration organic solvent.
