酿酒酵母几丁质合成酶1的表达与纯化
首发时间:2024-05-06
摘要:目的:构建酿酒酵母几丁质合成酶 1(Chitin synthase 1, CHS1)表达体系,以实现该蛋白的表达纯化。方法:从 NCBI 数据库中获得 CHS1 序列信息,构建 CHS1 过表达质粒。分别在原核系统与酿酒酵母中进行蛋白过表达,并通过亲和层析与尺寸排阻色谱进行蛋白纯化。结论:成功在酿酒酵母中表达并纯化 ScCHS1 蛋白。

Expression and purification of chitin synthase 1 in Saccharomyces cerevisiae
Abstract:Objective: This study is aimed to express and purify the Saccharomyces cerevisiae chitin synthase 1 (CHS1) by constructing a recombinant expression system for the protein. Methods: CHS1 gene sequence was obtained from NCBI database, and construct overexpression plasmids for 20 CHS1. Protein overexpression was independently conducted in both prokaryotic and yeast systems, followed by protein purification utilizing affinity chromatography and size exclusion chromatography. Results: Successful expression and purification of the ScCHS1 protein were achieved in Saccharomyces cerevisiae.
Keywords: Saccharomyces cerevisiae chitin synthase 1 protein recombinant expression membrane protein
