Abstract

The effects of E. coli proteins Integrative Host Factor (IHF) and NusA on the regulation of lambda cII gene expression are presented. As reported previously (Peacock et al. [1984] Proc. Natl. Acad. Sci. USA 81, 6009-6013), IHF stimulates the DNA-directed in vitro synthesis of cII protein or its first dipeptide, fMet-Val. Whereas NusA, by itself, has no effect on cII expression, the presence of NusA inhibits the IHF-mediated stimulation of cII synthesis.
