Regulated high efficiency expression of foreign genes in E. coli

摘要

(57) In general, [Abstract] The present invention relates to methods and materials for recombinant for carrying out the microbial production of useful polypeptides. More specifically, the expression vector systems that utilize the translation repressor system, the invention provides an inducible promoter system that can and to express foreign genes in E. coli, efficient and tightly regulated, was graded about the transcriptional regulatory protein that.
