Nucleic Acids Res 38:1636-51. 2010..Although GraL overexpression induces >/=3-fold transcriptional changes of over 100 genes, a direct target remains elusive...
Antagonistic regulation of Escherichia coli ribosomal RNA rrnB P1 promoter activity by GreA and DksAKatarzyna Potrykus
Laboratory of Molecular Genetics, NICHD, National Institutes of Health, Bethesda, Maryland 20892 2785, USA
J Biol Chem 281:15238-48. 2006..Our findings support the idea that a balance of the interactions between the three secondary channel-binding proteins and RNAP can provide a new mode for regulating transcription...
Effects on growth by changes of the balance between GreA, GreB, and DksA suggest mutual competition and functional redundancy in Escherichia coliDaniel Vinella

ppGpp is the major source of growth rate control in E. coliKatarzyna Potrykus
Laboratory of Molecular Genetics, Program in Genomics of Development, Eunice Kennedy Shriver NICHD, NIH, Bethesda, MD 20892 2785, USA
Environ Microbiol 13:563-75. 2011..We believe these findings strongly argue in favour of ppGpp and against redundant regulation of growth rate control by other factors in Escherichia coli and other enteric bacteria...
