ppGpp: a global regulator in Escherichia coli.
The small nucleotide ppGpp acts as a global regulator of gene expression in bacteria. Proteomic analysis of cells lacking ppGpp has shown that this nucleotide might affect many more genes thanExpand

Identical, independent, and opposing roles of ppGpp and DksA in Escherichia coli.
The recent discovery that the protein DksA acts as a coregulator of genes controlled by ppGpp led us to investigate the similarities and differences between the relaxed phenotype of a ppGpp-deficientExpand

Underproduction of sigma 70 mimics a stringent response. A proteome approach.
When Escherichia coli cells enter stationary phase due to carbon starvation the synthesis of ribosomal proteins is rapidly repressed. In a DeltarelA DeltaspoT mutant, defective in the production ofExpand
