在这里,我们综述了可用于表达主链环化多肽的不同生物化学方法,包括多肽和蛋白质。这些方法允许使用标准的重组DNA表达技术在体外或体内生产环状多肽。多肽环化为研究拓扑结构对蛋白质稳定性和折叠动力学的影响提供了有价值的工具。此外,能够以生物合成的方式获得主链环化多肽,使得生产基因编码的环多肽文库成为可能。这种文库的生产以前局限于合成化学领域,现在为生物学家提供了访问高度多样化和稳定的分子文库的途径,这些分子文库可以使用高通量方法进行筛选,以快速选择具有新生物活性的新的环状多肽序列。
Here we review the different biochemical approaches available for the expression of backbone-cyclized polypeptides, including peptides and proteins. These methods allow for the production of circular polypeptides either in vitro or in vivo using standard recombinant DNA expression techniques. Polypeptide circularization provides a valuable tool to study the effects of topology on protein stability and folding kinetics. Furthermore, having biosynthetic access to backbone-cyclized polypeptides makes the production of genetically-encoded libraries of cyclic polypeptides possible. The production of such libraries, which was previously restricted to the domain of synthetic chemistry, now offers biologists access to highly diverse and stable molecular libraries that can be screened using high-throughput methods for the rapid selection of novel cyclic polypeptide sequences with new biological activities.
