A comparison of structural and evolutionary attributes of Escherichia coli and Thermus thermophilus small ribosomal subunits: signatures of thermal adaptation. [PDF]
Here we compare the structural and evolutionary attributes of Thermus thermophilus and Escherichia coli small ribosomal subunits (SSU). Our results indicate that with few exceptions, thermophilic 16S ribosomal RNA (16S rRNA) is densely packed compared to

Selection of reference genes for expression analysis using quantitative real-time PCR in the pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera, Aphidiae). [PDF]
To facilitate gene expression study and obtain accurate qRT-PCR analysis, normalization relative to stable expressed housekeeping genes is required. In this study, expression profiles of 11 candidate reference genes, including actin (Actin), elongation ...

Computer modeling 16 S ribosomal RNA [PDF]
A three-dimensional structure for 16 S RNA has been produced with a computer protocol that is not dependent on human intervention. This protocol improves upon traditional modeling techniques by using distance geometry to fold the molecule in an objective and reproducible fashion.

The structure of a methylated tetraloop in 16S ribosomal RNA [PDF]
Ribosomal RNAs contain many modified nucleotides. The functions of these nucleotides are poorly understood and few of them are strongly conserved. The final stem loop in 16S-like rRNAs is an exception in both regards. In both prokaryotes and eukaryotes, the tetranucleotide loop that caps the 3'-terminal stem contains two N6, N6-dimethyladenosine ...

Action spectra for UV-light induced RNA–RNA crosslinking in 16S ribosomal RNA in the ribosome [PDF]
UV irradiation induces intramolecular crosslinks in ribosomal RNA in the ribosome. These crosslinks occur between nucleotides distant in primary sequence and they are specific, limited in number and have crosslinking efficiencies sufficient to allow their use in monitoring conformational changes.

Mutations in 16S ribosomal RNA disrupt antibiotic-RNA interactions. [PDF]
Two of six mutations at a base-paired site in Escherichia coli 16S rRNA confer resistance to nine different aminoglycoside antibiotics in vivo. Chemical probing of mutant and wild-type ribosomes in the presence of paromomycin indicates that interactions between the antibiotic and 16S rRNA in mutant ribosomes are disrupted.
