Abstract: The nucleosides are used extensively,and microbial fermentation is one of main methods of producing it. The secretion of nucleoside in microbial cells plays a critical role for high-yield nucleoside. There are many transport proteins as the role of transportation in the cell membrane,which are involved in the secretion of metabolites. Here,this article mainly elaborates the role of nucleoside transport proteins such as NupG and NupC during the nucleoside secretion process in microbial cells. Additionally,the effects of modification for transport protein on nucleoside biosynthesis were introduced,aiming at providing evidence for the breeding strategy of engineering high-yield strains.

Key words: microbes, nucleoside transporter, NupC, NupG
