5-Bromouracil-Induced Filaments of Escherichia coli
A dinucleoside monophosphate was isolated from 5-bromouracil-induced filaments of a thymine auxotroph of Escherichia coli K-12. The dinucleoside monophosphate was fractioned from a ["C]5-bromouracil-labeled perchloric acid extract using Dowex-1-formate ion-exchange chromatography. Sephadex chromatography revealed its molecular weight to be 710. Snake venom phosphodiesterase digest of the dinucl...
متن کامل3',5'-cyclic adenosine monophosphate-requiring mutants of Escherichia coli.
Mutants that require exogenous 3',5'-cyclic adenosine monophosphate (cAMP) for exponential growth were isolated from strains deficient in adenyl cyclase. Studies of one strain showed that cAMP is not incorporated into macromolecules; instead, it seems to have a regulatory function, i.e., in media lacking cAMP, cells form ribonucleic acid (RNA) and protein at linear rather than exponential rates...

متن کاملDifferential binding of cyclic adenosine 3' ,5'-monophosphate to the cyclic adenosine 3' ,5'-monophosphate receptor protein in Escherichia coli.
Binding of cyclic adenosine 3' ,5'-monophosphate (cAMP) by the cAMP receptor protein in crude cell-free extracts of Escherichia coli was characterized. When cell were grown in glucose, binding was inhibited 50% relative to extracts from cells grown with succinate as carbon source . This inhibition could be relieved by dialysis.
متن کاملHost-induced modification-restriction and the utilization of 5-bromouracil by thymineless mutants of Escherichia coli.
An m(k) (-)r(k) (-) mutation exerted no measurable effect on 5-bromouracil incorporation by a thymineless derivative of Escherichia coli K.
