摘    要:将蓝藻PCC7120细菌光敏色素缺失突变体AphA(26-320)基因和血红素氧化酶(h01)及胆绿素还原(PcyA)的基因共同转化E.Coil BL21(DE3),在IPTG的诱导下实现体内共同表达,进行体内重组,生成了具有可逆光致变色活性的AphA(26-320)-PCB,对重组茵的培养条件,诱导条件进行优化,确定适合合成AphA(26-320)-PCB的培养时间,诱导温度,摇床振荡速度等。

关 键 词:细菌光敏色素  体内重组  诱导表达  优化

Abstract:The aphA (26-320) was introduced into E. Coli BL21 (DE3) together with genes hol (encoding heme oxygenase) and pcyA to realize the autoassembly of the Cyanobacterial phytochrome AphA(26-320) and the PCB. Upon induction,recombinant E. Coli used the cellular pool of heme to produce AphA (26-320)-PCB with spectroscopic properties similar to those of the same protein produced endogenously in cyanobacteria, AphA(26-320)- PCB was red/infrared (R/FR)photochromic. After studying on the cultural and inducement condition of recombi- nant AphA(26-320)-PCB,The experiment condition was optimized to determine the suitable inducement tempera- ture and time.
Keywords:AphA(26-320)-PCB  reconstitution in vivo  inducment expression  expression optimization
