Abstract excerpt
The stringent response is one of the most important regulatory systems in bacteria for adaptation to environmental stresses such as amino acid starvation. This response is mediated by an unusual nucleotide, guanosine 3',5'-bis(pyrophosphate) (ppGpp), the levels of which are controlled by two enzymes, RelA and SpoT. ppGpp dramatically influences a broad range of physiological activities in bacterial cells,...
