查询词典 mutations

His concept is that you use the dugs which may induce mutation as early as several months or sometimes several weeks, that's why he has to check the DNA mutations, but there are now some drugs available who are OK for 5 years. If so, why you have to worry about mutation by performing expensive DNA frequency.

Keeffe教授的概念是指如果你所使用的药物是在用药几周或者几个月后就会引起突变的话，在这种情况下就需要检测HBV DNA，而对于5年耐药率都很低的药物来说，就没有必要如此频繁地进行昂贵的检测了。

In order to study the effects of 3 protein-4.2 point mutations associated with HS, we have cloned four recombinant fusion proteins: GST-P4.2 (31-200) D175Y, GST-P4.2 (31-200) D175Y, GST-P4.2 (100-260) D175Y, GST-P4.2 (31-200) A142T with pointmutation, to do prokaryotic expression, and tested their interactions with ankyrin by Far-Western blot and Pull-down assay, but there were no evidences to show these mutated proteins can bind to ankyrin except GST-P4.2 (31-200) A142T.

于是我们采用了点突变的方法，克隆表达了4种重组的突变蛋白GST-P4.2(31-200)D175Y、GST-P4.2(31-200)D175Y、GST-P4.2(100-260)D175Y，GST-P4.2(31-200)A142T，发现第175位氨基酸残基的突变使得相应的重组蛋白均不能与ankyrin直接相互作用，而第142位氨基酸残基的突变对P4.2与ankyrin之间的相互作用没有影响，这说明第175位氨基酸对于P4.2与ankyrin的结合是非常重要的，很可能是一个关键位点。
