Abstract

Two papers in this issue of Molecular Microbiology from Carol Gross and colleagues describe experiments that investigate how two alternative Escherichia coli sigma proteins recognize target promoter -10 regions. A combination of genetics, biochemistry and bioinformatics is used to show that determinants in two adjacent domains of the sigma proteins contact discrete sequence elements in the -10 regions.
