Abstract

The binding has been studied of Escherichia coli RNA-polymerase to the fragments of lambda DNA obtained by digestion with restriction endonucleases BsuI, HindIII, BamHI, EcoRI and HindII + III. There are at least six sites of RNA-polymerase binding in the b2-region. In vitro transcription of those BsuI-fragments of the b2-region which contain six binding sites is rightward. Therefore, the fragments contain promoters rather than mere RNA-polymerase binding sites. One of the promoters of the b2 region named patt was calculated to be about 50 bp to the left of the att site. We postulate that this promoter might correspond to the hef-target which was described as important for the site-specific recombination.
