To explore the effect of C-terminal region residues on the molecular conformation and enzymatic activity of a novel cyclic imide hydrolase (CIH), several mutants of CIH, truncated or substituted at C-terminal residues, were designed on the basis of its gene sequence.
为了研究一个新环酰亚胺水解酶(CIH)C端区残基对酶分子构象及酶活性的影响,设计了C末端缺失1~4个氨基酸残基以及C-末端2个Lys替代为2个Glu或2个Leu的突变酶,以野生型酶基因重组质粒pE-cih293为模板,在相应引物存在下,通过PCR扩增获得突变的CIH基因片段。
