DNA transducing vector and microorganism containing it.

摘要

Described is a DNA transducing vector carrying the P1 promoter derived from ribosomal RNA of Escherichia coli, a microorganism containing a DNA transducing vector carrying this P1 promoter, a recombinant DNA carrying this P1 promoter, a microorganism containing this recombinant DNA, a microorganism containing said recombinant DNA and E. coli I-001 and I-002, ATCC No. 31 698 and 31 699. The P1 promoter derived from ribosomal RNA of E. Coli has a stronger activity than the lactose promoter; see also Fig. 1.
