Recombinant DNA for the repressible and inducible expression of foreign genes

摘要

A recombinant DNA which contains the consensus sequence <IMAGE> and a promoter which has the DNA sequence GGN10GC, where the consensus sequence is preferably located 15 to 150 base pairs upstream of the transcription start of a gene which is expressed under the control of the promoter, and the promoter is located between the consensus sequence and the trascription start, makes inducible and repressible expression of a foreign gene possible.
