Changes in Escherichia coli rRNA promoter activity correlate with changes in initiating nucleoside triphosphate and guanosine 5' diphosphate 3'-diphosphate concentrations after induction of feedback control of ribosome synthesis.

abstract：:We screened Salmonella typhimurium, Citrobacter freundii, Klebsiella pneumoniae, Shigella boydii, and many isolates of Escherichia coli for DNA sequences homologous to those encoding each of two unrelated type I restriction and modification systems (EcoK and EcoA).
