Requirement for the molecular adapter function of StpA at the Escherichia coli bgl promoter depends upon the level of truncated H-NS protein.

Molecular microbiology - 1 Nov 2001

Free A, Porter M E, Deighan P, Dorman C J

Abstract excerpt

Truncated derivatives of the Escherichia coli nucleoid-associated protein H-NS that lack the DNA-binding domain remain competent for silencing of the cryptic bgl operon in vivo. Previous studies have provided evidence for the involvement of either the homologous nucleoid protein StpA or the alternative sigma factor RpoS in this unusual silencing mechanism. Here, we rationalize this apparent discrepancy. We show...
