摘要:
为了得到右旋的2-氨基丁酸,对2-氨基丁酸的拆分进行了研究.通过从猪肾中提取的氨基酰化酶选择性地水解(R,S)-2-N-乙酰氨基丁酸,得到了(S)-2-氨基丁酸,旋光度 = +21.58°(C=2,5 mol/L HCl),收率为71.8%.试验结果表明最佳拆分条件为:底物浓度为0.1 mol/L;底物与酶质量比为100∶1;pH 6.8~7.0;温度为37 ℃;反应时间为24 h.
Abstract:
A study was made on the resolution of 2-aminobutyric acid in order to obtain dextrogyarte 2aminobutyric acid.In our experiment,(S)-2aminobutyric acid was resolved from (R,S)-2-aminobutyric acid by selective hydrolyzation of (R,S)-2-N-acyl aminobutyric acid which in the presence of acylase was derived from the kidney of pigs.The optical rotation=+21.58°(C=2,5N HCl) and the yield of (S)-2-aminobutyric acid is 71.8%.The experimental results showed that the best hydrolytic conditions are as follows: the concentration of the substrate is controlled to about 0.1 mol/L;m(subsrate):m(enzyme)=100:1;pH value of reaction system is 6.8~7.0;reaction temperature is 37 ℃ and reaction time is 24 h.
