Inhibition of protein synthesis in Escherichia coli by expression of RNAs containing multiple ribosome binding sites
To get together the biosynthesis of chemical biological synthesis mRNA
2014/12/11
Biologically synthesized poly(α,L-glutamic acid) (PLGA) can be chemically modified to form monodisperse poly(γ-benzyl α,L-glutamate) (PBLG). This material shows rare smectic ordering where macromolecu...

Hsp70 Protein aggregation Enzyme Polypeptide Protein function Nucleotides. The ATP hydrolysis
2014/12/11
The Hsp70 family molecular chaperones prevent protein aggregation under heat shock conditions. They are highly conserved, and have a N-terminal ATPase domain, which binds and hydrolyzes ATP, and a C-t...

E.coli的Prlc基因产物对OmpA前体蛋白翻译后转位的功能
OmpA前体 prlc基因 转位 大肠杆菌膜囊
2007/12/19
摘要 使用OmpA为指示蛋白,我们证实了prlc基因产物主要定位在胞液中,在分泌蛋白的转位过程中,它不是一个必需因子,但它的确涉及OmpA前体的转位定域。使用印迹试验证明它可能是一个信号肽水解酶。
人白介素6受体功能区片段在E.coli中的表达
人白介素6受体 克隆和表达 大肠杆菌 免疫印迹
2007/12/17
摘要 通过DNA体外重组技术,以pET-3b为表达载体,构建了重组表达质粒pET-6R(B)和PET-6R(B)4,分别编码28kD的hIL-6R配基结合区片段及其53kD的二联体蛋白,并为酶切分析和DNA序列分析所证实。SDS-PAGE分析表明,含有重组表达质粒的菌株可分别表达出28kD的蛋白rIL6R-28和53kD的rIL6R-53。重组蛋白分别占菌体总蛋白的45%和29%左右。重组蛋白主要...
摘要 采用PCR技术从E.coli基因组片段中克隆出碱性磷酸酯酶(PhoA)的启动子和信号肽序列.在PhoA启动予5'端设计了EcoRⅠ酶切位点,在信号肽编码序列3'端设计了HindⅢ酶切位点.将PCR产物酶切后EcoRⅠ-HindⅢ片段克隆至pBR322的EcoRⅠ-HindⅢ位点,组构出含有PhoA启动子和信号肽序列的分泌表达载体pBM-Pho-1.之后将人表皮生长因子的成熟肽基因克隆至该载体...
