简单介绍

pMal-c5X大肠pMal系列表达质粒其目的是产生maltose -binding protein(MBP)fuUNK，在这里，可以将感兴趣的蛋白质与特定蛋白酶因子Xa分离。用这个载体进行的MBP融合表达为细胞质。MBP已经被设计用于对直链淀粉的更紧密的结合。pMal-c5X大肠pMal系列表达质粒一个基因或开放的阅读框插入到向量多连结器的限制位点，在相同的平动读帧中为男性基因(编码maltose -binding protein)。由此产生的融合蛋白可通过直链淀粉亲和层析纯化。四种氨基酸的序列编码在XmnI位点上游。

质粒简介

The vector pMAL-c5X is designed to produce maltose-binding protein (MBP) fusions, where the protein of interest can be cleaved from MBP with the specific protease Factor Xa . MBP fusions made with this vector are expressed cytoplasmically. The MBP has been engineered for tighter binding to amylose resin. A gene or open reading frame is inserted into a restriction site of the vector polylinker, in the same translational reading frame as the malE gene (encoding maltose-binding protein). The fusion protein thus produced can be purified by amylose affinity chromatography. The sequence coding for the four amino acids Ile-Glu-Gly-Arg is present just upstream of the XmnI site. This allows the protein of interest to be cleaved from maltose-binding protein with the specific protease Factor Xa. Fragments inserted in the XmnI site (cleaves GAAGG↓ATTTC) will produce a fusion protein that, after Factor Xa cleavage, contains no vector-derived residues on the protein of interest.
