| Popis: | Summary We have reexamined the intracellular levels of guanosine 5′-diphosphate 3′-diphosphate in a prototrophic stringent strain of Escherichia coli during balanced growth at eight different growth rates. No regular inverse relationship between the basal levels of this nucleotide and the RNA content per unit DNA was observed. Thus, it is concluded that the cellular capacity to accumulate RNA is not directly related to the basal level of this nucleotide. It was also observed that significant quantities of this nucleotide accumulated extracellularly to varying degrees depending on the carbon source used. |
