Polyamine limitation of growth slows the rate of polypeptide chain elongation in Escherichia coli.
The rate of polypeptide chain elongation during steady-state, polyamine-limited growth of a mutant of Escherichia coli was measured by two independent techniques. Analysis of polysome patterns gave values of 17.5 and 9.5 amino acids per s at 37 C in unstarved and polyamine-limited cells, respectively. From the kinetics of entry of labeled amino acids into polypeptides of defined molecular weigh...
متن کاملEfficiency of thymidine incorporation in Escherichia coli B-r as a function of growth rate.
Short-term labeling with radioactive thymidine led to inaccurate estimates of deoxyribonucleic acid synthesis at some growth rates in steady-state cultures of Escherichia coli B/r. Estimates were corrected in chemostat cultures by adding adenosine, a known inhibitor of thymidine phosphorylase.
متن کاملInitiator (DnaA) protein concentration as a function of growth rate in Escherichia coli and Salmonella typhimurium.
The DnaA protein concentration was determined in five different Escherichia coli strains and in Salmonella typhimurium LT2 growing at different growth rates. The DnaA protein concentration was found to be invariant over a wide range of growth rates in the four E. coli K-12 strains and in S. typhimurium. In E. coli B/r the DnaA protein concentration was generally higher than in the K-12 strains,...
متن کاملVarying rate of RNA chain elongation during rrn transcription in Escherichia coli.
The value of the rRNA chain elongation rate in bacteria is an important physiological parameter, as it affects not only the rRNA promoter activity but also the free-RNA polymerase concentration and thereby the transcription of all genes. On average, rRNA chains elongate at a rate of 80 to 90 nucleotides (nt) per s, and the transcription of an entire rrn operon takes about 60 s (at 37 degrees C)...
متن کاملModelling the growth rate of Escherichia coli as a function of pH and lactic acid concentration.
The growth rate responses of Escherichia coli M23 (a nonpathogenic strain) to suboptimal pH and lactic acid concentration were determined. Growth rates were measured turbidimetrically at 20 degrees C in the range of pH 2.71 to 8.45. The total concentration of lactic acid was fixed at specific values, and the pH was varied by the addition of a strong acid (hydrochloric) or base (sodium hydroxide...
