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 ...

Preparation of guanosine tetraphosphate (ppGpp) and guanosine pentaphosphate (pppGpp) from Escherichia coli ribosomes

Analytical Biochemistry, 1974
Abstract A means of preparative enzymatic synthesis of guanosine tetraphosphate (ppGpp), guanosine pentaphosphate (pppGpp), and related derivatives is deseribed. The Escherichia coli ribosomes can be recovered, stored, and used repeatedly as a source of synthetic activity.

Accumulation and turnover of guanosine tetraphosphate in Escherichia coli

Journal of Molecular Biology, 1972
Abstract 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
