Accumulation of guanosine tetraphosphate induced by polymixin and gramicidin in Escherichia coli
Biochimica Et Biophysica Acta - General Subjects, 1983 The effects of two polypeptide antibiotics, polymixin B and gramicidin S, on the intracellular pool size and turnover of guanosine tetraphosphate (ppGpp) were analyzed in stringent (relA+) and relaxed (relA) strains of Escherichia coli. When either one of these two drugs was added to stringent bacteria cultures at a final concentration that blocked ...

Accumulation and turnover of guanosine tetraphosphate in Escherichia coli
Journal of Molecular Biology, 1972Abstract A strain ofEscherichia coli B possessing a temperature-labile valyl-transfer RNA synthetase (strain NF 342) has been used to study guanosine tetraphosphate metabolism. Culturing this strain at a variety of temperatures intermediate between the permissive and non-permissive (30 to 42 °C) yielded a range of growth rates, presumably as a result
