title: Intracellular 5',5'-dinucleoside polyphosphate levels remain constant during the Escherichia coli cell cycle.
abstract: All AppppN and ApppN nucleotides (N = A, C, G, or U) occur in Escherichia coli. Measured cellular concentrations were 2.42 microM AppppA, 0.61 microM AppppC, 0.95 microM AppppG, 1.17 microM AppppU, 0.47 microM ApppA, 0.14 microM ApppC, 0.20 microM ApppG, and 0.12 microM ApppU. These concentrations remained constant during the cell cycle in synchronized exponentially growing cells.
