Gene expression in Streptomyces: construction and application of promoter-probe plasmid vectors in Streptomyces lividans.

Abstract

Promoter-probe plasmid vectors were constructed for Streptomyces lividans using expression of the Escherichia coli chloramphenicol acetyltransferase gene as an indicator of promoter activity. These vectors have been used to isolate and to study the activity of DNA sequences that contain transcriptional control signals from Streptomyces, Bacillus licheniformis, E. coli, and Serratia marcescens. Studies of these promoter regions in heterospecific hosts indicate that genus or species-specific factors may present barriers to the expression of bacterial genetic material in certain heterologous cellular environments. While promoter regions isolated from E. coli, S. marcescens and B. licheniformis all appear to be recognized by the RNA polymerase of S. lividans, the Streptomyces transcriptional control signals isolated do not appear to function normally in E. coli.
