摘要: 以酵母作为宿主生产的蛋白在生活和医疗中有着广泛应用,但其特有的对蛋白进行高甘露糖基化修饰会造成蛋白免疫原性改变、半衰期缩短等负面影响。通过工程改造,能够减弱酵母中蛋白的甘露糖基化修饰程度,且在毕赤酵母(Pichia pastoris)中已经能够产生唾液酸化糖蛋白。介绍酵母系统在生产药物蛋白方面的应用,简述酵母N-糖基化修饰过程以及目前酵母人源化研究进展。

Abstract: Proteins produced by yeast as hosts are widely used in life and medical treatment, but their unique modification of protein with high mannose glycosylation will cause negative effects such as changes in protein immunogenicity and shortening of half-life. Through engineering modification, the degree of mannose modification of proteins in yeast can be reduced, and sialic acid glycoproteins have been produced in Pichia pastoris. The application of the yeast system in the production of pharmaceutical proteins was introduced. The modification process of yeast N-glycosylation and the research progress of yeast humanization were reviewed.

Key words: yeast, N-glycosylation, humanization, glycoprotein
