Ribosomal RNA is the catalytic portion of ribosomes, and undergoes a variety of conformational changes during translation. Structural changes in ribosomal RNA can be facilitated by the presence of modified nucleotides. Helix 31 of bacterial 16S ribosomal

Correcting a SHAPE-directed RNA structure by a mutate-map-rescue approach [PDF]
The three-dimensional conformations of non-coding RNAs underpin their biochemical functions but have largely eluded experimental characterization. Here, we report that integrating a classic mutation/rescue strategy with high-throughput chemical mapping enables rapid RNA structure inference with unusually strong validation. We revisit a paradigmatic 16S

Models of protein production along the cell cycle: an investigation of possible sources of noise [PDF]
In this article, we quantitatively study, through stochastic models, the efects of several intracellular phenomena, such as cell volume growth, cell division, gene replication as well as fuctuations of available RNA polymerases and ribosomes. These phenomena are indeed rarely considered in classic models of protein production and no relative ...

Euglena gracilis chloroplast ribosomal RNA transcription units. II. Nucleotide sequence homology between the 16 S–23 S ribosomal RNA spacer and the 16 S ribosomal RNA leader regions. [PDF]
The DNA sequences of two segments of the ribosomal RNA transcription units of Euglena gracilis Pringsheim strain Z chloroplast DNA have been determined. The first is from the 16 S to 23 S rRNA spacer region. The nucleotide sequence determined includes 64 bp from the 3'-end of the 16 S rRNA gene, the adjacent 87-bp spacer containing 68A-T base pairs, a ...

The complete mitochondrial genome of Anas penelope (Anatidae: Anas)
The complete mitochondrial DNA genome of the Eurasian Wigeon, Anas penelope, was mapped by the next-generation sequencing and Mega 7.0. The circular mitogenome (16,596 bp in length) contains 13 protein-coding genes, 2 rRNA genes (12S ribosomal RNA and ...

Choice of 16S ribosomal RNA primers affects the microbiome analysis in chicken ceca
We evaluated the effect of applying different sets of 16S rRNA primers on bacterial composition, diversity, and predicted function in chicken ceca. Cecal contents from Ross 708 birds at 1, 3, and 5 weeks of age were collected for DNA isolation.

Transcriptional profiling of colicin-induced cell death of Escherichia coli MG1655 identifies potential mechanisms by which bacteriocins promote bacterial diversity [PDF]
We report the transcriptional response of Escherichia coli MG1655 to damage induced by colicins E3 and E9, bacteriocins that kill cells through inactivation of the ribosome and degradation of chromosomal DNA, respectively. Colicin E9 strongly induced the

Next-generation Sequencing of 16S Ribosomal RNA Gene Amplicons [PDF]
One of the major questions in microbial ecology is "who is there?" This question can be answered using various tools, but one of the long-lasting gold standards is to sequence 16S ribosomal RNA (rRNA) gene amplicons generated by domain-level PCR reactions amplifying from genomic DNA.

Chromosomal 16S Ribosomal RNA Methyltransferase RmtE1 in Escherichia coli Sequence Type 448
We identified rmtE1, an uncommon 16S ribosomal methyltransferase gene, in an aminoglycoside- and cephalosporin-resistant Escherichia coli sequence type 448 clinical strain co-harboring blaCMY-2.
