The specific activities of arginyl- glutamyl- seryl-, and valyl-transfer ribonucleic acid (tRNA) synthetases were measured in the wild-type and mutant strains of Salmonella typhimurium LT2 and Escherichia coli B/r. In media restricted only by carbon and energy source availability, the specific activities of all four enzymes were proportional to the growth(More)
The arginyl and valyl transfer ribonucleic acid synthetases (EC 6.1.13 and EC 6.1.1.9, respectively) in various strains of Escherichia coli and Salmonella typhimurium were measured over a wide range of steady state growth rates. Both enzymes were found to increase approximately 2.5-fold in specific activity over a 7-fold increase in growth rate. Appropriate(More)
