定向进化 meaning in Chinese

orthogenesis

New and highly effective strategies for directed enzyme evolution in vitro have been developed in the protein engineering
酶的体外定向进化是蛋白质工程的新策略。
Therefore , we selected the method of directed evolution to modify the a - aldc gene in order to obtain the mutants with high enzyme activity in low temperature
为此，我们采用定向进化的方法对酶基因进行改造，以期获得更适合于啤酒发酵的表达- aldc的工程菌株。
This review emphasizes some important aspects for the control of lipase enantioselectivity : medium engineering , substrate engineering , modification of enzyme and directed evolution
文章讨论了调控脂肪酶对映体选择性的几种方法：反应介质工程、底物分子工程、酶分子修饰和定向进化。
Approximately 7000 colonies were screened . one mutant was obtained , and its enzyme activity is 2 . 09 - fold higher than that of wild - type a - aldc in low temperature . the two nucleotide substitutions were occurred in the evolved a - aldc gene
根据定向进化的基本思想，我们利用易错pcr的方法，筛选了近7000个菌落，最终得到了一株在低温下也有较高酶活力的突变体。
