Role of cyclic adenosine 3',5'-monophosphate on cessation of respiration in ultraviolet-irradiated Escherichia coli.
نویسندگان
چکیده
The addition of cyclic adenosine 3',5'-monophosphate (cAMP) to ultraviolet-irradiated Escherichia coli B/r cultures causes additional cells to cease respiring and to die. These effects of cAMP are greater on glucose-grown cells, where the effects of ultraviolet radiations alone are smaller and where the intracellular concentrations of cAMP are known to be lower.

Role of Pyridine Nucleotides in the Control of Respiration in Ultraviolet-Irradiated Escherichia coli B/r Cells.
Escherichia coli B/r cells grown on glycerol-containing medium and irradiated with ultraviolet light to about 1% survival respire for about 1 hr and then cease completely for several hours. The results of studies on cell-free respiration and analyses of pyridine nucleotide levels at various times after ultraviolet irradiation show that the cessation of respiration is associated with two changes...
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 کاملRequirement of adenosine-3',5'-cyclic monophosphate for L-arabinose isomerase synthesis in Escherichia coli.
Adenosine-3', 5'-cyclic monophosphate (cyclic AMP) is essential for the synthesis of l-arabinose isomerase in Escherichia coli. Cyclic AMP appears to be required for the transcription of deoxyribonucleic acid into messenger ribonucleic acid (RNA), since the enzyme synthesis is not observed in induced cells to which cyclic AMP is added after messenger RNA synthesis is arrested by rifampin or aft...
متن کاملRequirement of adenosine 3', 5'-cyclic phosphate for flagella formation in Escherichia coli and Salmonella typhimurium.
Adenosine-3',5'-cyclic phosphate (cyclic AMP) is absolutely required for flagella formation and, hence, motility in cyclic AMP-deficient mutants of Escherichia coli and Salmonella typhimurium.
متن کاملEffects of antipain (a protease inhibitor) on respiration, viability, and excision of pyrimidine dimers in UV-irradiated Escherichia coli cells.
The protease inhibitor antipain increases the effectiveness of UV irradiation on cessation of respiration and cell killing in Escherichia coli B/r cultures without affecting excision of pyrimidine dimers. The actions are similar to those caused by cyclic AMP in irradiated cultures.
