Ribosomal precursors and ribonucleic acid synthesis in Escherichia coli.
Ribosomes and immature ribonucleoprotein particles were isolated from extracts of log-phase cells grown under various conditions. Quantitative measurements were made to determine the relative amounts of immature particles present in the extracts. The results indicate that the steady-state level of ribosomal precursors accounted for essentially a constant fraction of the total ribonucleic acid (...
متن کاملDeoxyribonucleic acid-ribonucleic acid hybridization studies on the L-Arabinose operon of Escherichia coli B-r.
An increase in the rate of synthesis of ara-specific messenger ribonucleic acid as measured by deoxyribonucleic acid-ribonucleic acid hybridization has been detected in the induced wild-type (ara(+)) strain of Escherichia coli B/r as compared with the uninduced control, thus providing evidence that regulation of the positively controlled l-arabinose operon is at the level of transcription.
متن کاملThreonyl-transfer ribonucleic acid synthetase and the regulation of the threonine operon in Escherichia coli.
Two threonine-requiring mutants with derepressed expression of the threonine operon were isolated from an Escherichia coli K-12 strain containing two copies of the thr operon. One of them carries a leaky mutation in ilvA (the structural gene for threonine deaminase), which creates an isoleucine limitation and therefore derepression of the thr operon. In the second mutant, the enzymes of the thr...
متن کاملStructure of the Escherichia coli S10 ribosomal protein operon.
The complete structure of the Escherichia coli S10 ribosomal protein operon is presented. Based on the DNA sequence, the deduced order of the 11 genes in the operon is rpsJ, rplC, rplD, rplW, rplB, rpsS, rplV, rpsC, rplP, rpmC, rpsQ. The estimated transcribed length of the operon is 5181 base pairs. Putative sequences involved in ribosome binding are discussed. The DNA sequence data corrects se...
متن کاملRegulation of ribosomal and transfer ribonucleic acid synthesis in Escherichia coli B-r.
The relative rates of tRNA, rRNA, and DNA synthesis were measured for steady state cultures of Escherichia coli B/r growing in succinate and glucose minimal media which support growth rates of 0.67 and 1.46 doublings per hour, respectively. Following a Z-fold increase in growth rate, the rate of tRNA synthesis increased approximately Z-fold relative to the rate of DNA synthesis and decreased 10...
