Fig. 2From: Systematic identification of a panel of strong promoter regions from Listeria monocytogenes for fine-tuning gene expressionSchematic diagram of constructed plasmid pERL3-Promoter-EGFP. The coding sequences of promoter regions and EGFP were cloned into the BamH I site. The promoters were used to express the EGFP reporter gene. pIL ori allowed for expression in Lm, and pBR ori allowed for expression in Escherichia coli [24]. The restriction site was BamH IBack to article page
