Ribonucleic Acid Synthesis and Glutamate Excretion in Escherichia coli
AUTOR(ES)
Broda, Paul
RESUMO
Cultures of Escherichia coli excreted glutamate into the medium when protein synthesis was blocked in RCrel strains or when it was blocked with chloramphenicol in either RCstr or RCrel strains. Both of these conditions resulted in continued ribonucleic acid (RNA) synthesis in the absence of protein synthesis. Glutamate was also excreted by both RCstr and RCrel strains when RNA synthesis was inhibited by uracil starvation or by treatment with actinomycin D. It is proposed that, in each of these cases, glutamate excretion resulted from an increase in the permeability of the cell membrane.
