摘要: Rhodococcus strains not only have been widely used in industries but also have a potential ability of producing new structural natural products. Integration of heterologous genes into chromosomes of Rhodococcus strains for gene expression can facilitate the studies and applications of these strains. A conjugation system was optimized in order to transfer enhanced green fluorescent protein (EGFP) encoding gene as a reporter from Escherichia coli into Rhodococcus erythropolis D-1. The influence of three native ribosome binding sites (RBSs) and two designed RBSs on the target protein production in R. erythropolis D-1 was also characterized. An efficient conjugation system of R. erythropolis D-1 was established to integrate EGFP gene into its chromosome. Among of five RBSs, RBS3 showed the highest translational activity in R. erythropolis D-1.
