Results of development of shuttle expressing plasmid vector Escherichia coli-Lactobacillus which allowed high level expression of heterologous genes in lactobacilli are represented. Vector pTRKH2 which is able to replicate in E. coli and in wide range of Gram-positive bacteria was used as the base. In order to provide high level of cloned gene expression constitutive-active synthetic promoter, site of initiation of translation, and terminator of transcription were introduced in the vector. Functional activity of this vector was confirmed using green fluorescent protein (GFP) gene from Aequoria victoria. Transformation of model strain by gfp gene-carrying plasmid resulted in appearance of typical fluorescent phenotype.
