In the regulation of gene expression in prokaryotes, anti-sigma factors bind to sigma factors and inhibit their transcriptional activity. Anti-sigma factors have been found in Escherichia coli, Salmonella, and T4 bacteriophage. Anti-sigma factors are antagonists to the sigma factors, which regulate numerous cell processes including flagellar production,...
