Structure 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...

Secondary structure of the leader transcript from the Escherichia coli S10 ribosomal protein operon.

Genetic analysis of the autogenous control of the S10 ribosomal protein operon of Escherichia coli has suggested that the secondary or tertiary structure of the leader transcript is important for this regulation. We have therefore determined the secondary structure of the leader by enzyme digestion and chemical modification. Our results suggest that the 172 base leader exists in two forms, diff...

The structure of a ribosomal protein S8/spc operon mRNA complex.

In bacteria, translation of all the ribosomal protein cistrons in the spc operon mRNA is repressed by the binding of the product of one of them, S8, to an internal sequence at the 5' end of the L5 cistron. The way in which the first two genes of the spc operon are regulated, retroregulation, is mechanistically distinct from translational repression by S8 of the genes from L5 onward. A 2.8 A res...

Phylogenetic analysis of L4-mediated autogenous control of the S10 ribosomal protein operon.

We investigated the regulation of the S10 ribosomal protein (r-protein) operon among members of the gamma subdivision of the proteobacteria, which includes Escherichia coli. In E. coli, this 11-gene operon is autogenously controlled by r-protein L4. This regulation requires specific determinants within the untranslated leader of the mRNA. Secondary structure analysis of the S10 leaders of five ...

Nucleotide sequence of the alpha ribosomal protein operon of Escherichia coli.

In Escherichia coli some 19 transcription units encoding the 52 ribosomal proteins are scattered throughout the genome. One of the units, the alpha operon, encodes genes for the ribosomal proteins S13, S11, S4 and L17 as well as the alpha subunit of RNA polymerase. We report here the complete 3.0 kb nucleotide sequence of the alpha operon. In addition, we have determined by S1 nuclease mapping ...
