3)  in vitro reconstitution
体外重组
1.
The activities of expressed proteins were studied through in vitro reconstitution tests,which showed ApcE(25-240) could bind covalently phycocyanobilin(PCB) in an autocatalytic reaction,in the presence of 4 mol/L urea necessary to so.
结果表明:在含有4 mol/L尿素的磷酸钾缓冲体系中,ApcE(25-240)脱辅基蛋白可与藻蓝胆素体外重组实现共价连接,获得的色素蛋白质具有最大吸收峰(λmax=656 nm)和荧光发射峰(λmax=670 nm),其余6个缺失突变体蛋白仅能与藻蓝胆素非共价连接,不能发生自催化重组。

CAS号:

性质:又称DNA重组体。两种或两种以上不同物种来源的DNA片断,用生物化学力法共价连接而成的DNA分子。通常指基因组的某一DNA片断,即目的基因与能进行自我复制的小分子载体DNA分子,如质粒、噬菌体或病毒连接构建的DNA分子。用序列特异的限制性内切酶在精确位点切割目的基因和载体DNA,再经DNA连接酶等方法拼接构成。导入合适的宿主细胞,可随细胞的繁殖扩增或表达,产生所需要的基因产物。
