【摘要】 乳酸菌食品级NICE系统是目前较理想的可控制蛋白质生产的食品级诱导表达系统。本实验构建的食品级表达载体pRNA48含α-aga食品级选择标记、θ型复制子和nisA启动子,与宿主菌L.lactisNZ9000共同构成乳酸乳球菌食品级NICE系统,可用于目的基因在乳酸乳球菌中高效诱导表达。更多还原

【Abstract】 The food-grade nisin-controlled expression (NICE) system of lactic acid bacteria (LAB) is the over-production and inducible expression system. The food-grade vector pRNA48 is based on the food-grade α-aga selectable marker, theta replcon, and nisA promoter to construct the Lactococcus lactis NICE system together with the L. Lactis NZ9000 for the food-grade inducible over-production expression of interesting gene in Lactococcus lactis.更多还原
