titleOfInvention |
A kind of synthesis and purification method of (R)-3-aminobutyric acid |
abstract |
The invention relates to a method for synthesizing and purifying (R)-3-aminobutyric acid. The present invention first provides a new aminotransferase, the amino acid sequence of which is shown in SEQ ID NO: 2, the enzyme can effectively catalyze the synthesis of (R)-3-amino crotonic acid without adding ammonium salts Butyric acid; the present invention also provides a high-density fermentation method, which can enable the engineering bacteria expressing the aminotransferase to achieve high-density growth in a short time, and to achieve high-efficiency expression of the aminotransferase; the present invention also provides a (R The method for separating and purifying )-3-aminobutyric acid can simply and efficiently obtain (R)-3-aminobutyric acid with a purity higher than 99% without complex membrane treatment equipment of different grades. |
