Abstract
The present invention provides a recombinant DNA, wherein it contains the consensus sequence: ##STR1## and a promoter which has the DNA sequence GGN.sub.10 GC. The present invention also provides a process for the isolation of this recombinant DNA, wherein a DNA sequence containing the consensus sequence is identified from a gene bank of a micro-organism, which contains a gene which is repressible by oxygen and inducible by formate under anaerobic conditions, isolated and combined with an appropriate promotor according to known methods. This recombinant gene can be used for the inducible and repressible expression of a foreign gene by bringing about the induction by formate under anaerobic conditions and the repression by oxygen.
