Ribosome Maturation of Escherichia coli Growing at Different Growth Rates

摘要: The data reported here are consistent with the hypothesis that rate of ribosome assembly in vivo approximates a constant fraction generation time for four rates studied. This conclusion is indicated by following. (i) There an increased lag period before radioisotopically labeled uracil appears 23 and 16S ribosomal ribonucleic acid 70S ribosomes as function growth rate. (ii) necessary 3H-uracil 43S ribonucleoprotein precursor to 50S subunit assume position at sucrose gradients greatly inversely
