Problems solved by technology

[0008] However, there are no relevant reports at home and abroad on the production of coenzyme Q10 by using enzyme engineering methods
[0009] This shows that the above-mentioned existing method for producing coenzyme Q10 obviously still has inconvenience and defects in the method, and needs to be further improved urgently.
In order to solve the problems existing in the method of producing coenzyme Q10, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable way to solve the above problems in general methods

Abstract

The present invention relates to a method for producing coenzyme Q10 using an enzyme engineering method, using coenzyme Q0 and decapolyisoprene as raw materials, or using coenzyme Q1 and solanesol as raw materials, wherein Phosphorylation of polyisoprene, bromination of solanesol; under the action of polymerase, under the condition of 40 ℃ ~ 60 ℃, the synthesis reaction of coenzyme Q10 is carried out in the reactor, followed by extraction, concentration and crystallization , and dried to obtain the finished product. The polymerase is obtained through the following steps: selecting Rhodopseudomonas photosynthetic bacteria containing coenzyme Q10 and culturing; breaking the bacterial cells and precipitating with 3% saline; separating the precipitate to obtain the polymerase. The invention has specificity, improves the reaction efficiency and improves the product quality. Coenzyme Q10 produced by the enzyme engineering method has no isoprene with cis structure in its side chain, and the biological activity of the product is the same as that of the product produced by the microbial fermentation method, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a method for producing coenzyme Q10, in particular to a method for producing coenzyme Q10 by using an enzyme engineering method. Background technique [0002] Coenzyme Q10, also known as ubiquinone 10, is an over-the-counter drug included in the Pharmacopoeia in my country. Coenzyme Q10 is a fat-soluble quinone, which is orange-yellow crystal at room temperature, and its melting point is 48°C. It is odorless and tasteless. It is named after the degree of polymerization of pentadiene group is 10, and it is a quinone ring compound. The physiological function of coenzyme Q10 mainly comes from the oxidation-reduction properties of the quinone group and the physical properties of the isoprenoid side chain. It has two main functions in the human body. One is to have an obvious anti-lipid peroxidation effect; Nutrients play an important role in the conversion of nutrients into energy in the mitochondria. Its quinone ring plays the ...
