Differential binding profiles of StpA in wild-type and h-ns mutant cells: a comparative analysis of cooperative partners by chromatin immunoprecipitation-microarray analysis.

We performed chromatin immunoprecipitation-microarray analysis to investigate differences in function between StpA and H-NS in Escherichia coli cells. StpA binding regions essentially overlap those of H-NS in wild-type cells, while they are reduced to one-third in the hns mutant. The H-NS binding profile was unaffected by stpA inactivation.
