Inferring long memory processes in the climate network via ordinal pattern analysis [PDF]

, 2011
We use ordinal patterns and symbolic analysis to construct global climate networks and uncover long and short term memory processes. The data analyzed is the monthly averaged surface air temperature (SAT field) and the results suggest that the time ...

Structural basis of ribosomal 30S subunit degradation by RNase R

Nature
Protein synthesis is a major energy-consuming process of the cell that requires the controlled production1–3 and turnover4,5 of ribosomes. Although the past few years have seen major advances in our understanding of ribosome biogenesis, structural ...

Binding properties of YjeQ (RsgA), RbfA, RimM and Era to assembly intermediates of the 30S subunit

Nucleic Acids Research, 2016
Our understanding regarding the function of YjeQ (also called RsgA), RbfA, RimM and Era in ribosome biogenesis has been derived in part from the study of immature 30S particles that accumulate in null strains lacking one of these factors.

Structural Insights into the Distortion of the Ribosomal Small Subunit at Different Magnesium Concentrations

Biomolecules, 2023
Magnesium ions are abundant and play indispensable functions in the ribosome. A decrease in Mg2+ concentration causes 70S ribosome dissociation and subsequent unfolding.

Structure of a 30S pre-initiation complex stalled by GE81112 reveals structural parallels in bacterial and eukaryotic protein synthesis initiation pathways

Nucleic Acids Research, 2016
In bacteria, the start site and the reading frame of the messenger RNA are selected by the small ribosomal subunit (30S) when the start codon, typically an AUG, is decoded in the P-site by the initiator tRNA in a process guided and controlled by three ...

30S Beam Development and X-ray Bursts

, 2010
Over the past three years, we have worked on developing a well-characterized 30S radioactive beam to be used in a future experiment aiming to directly measure the 30S(alpha,p) stellar reaction rate within the Gamow window of Type I X-ray bursts.

Nuclear structure of 30S and its implications for nucleosynthesis in classical novae

, 2012
The uncertainty in the 29P(p,gamma)30S reaction rate over the temperature range of 0.1 - 1.3 GK was previously determined to span ~4 orders of magnitude due to the uncertain location of two previously unobserved 3+ and 2+ resonances in the 4.7 - 4.8 MeV ...

Inhibition of translation initiation complex formation by GE81112 unravels a 16S rRNA structural switch involved in P-site decoding [PDF]

, 2016
In prokaryotic systems, the initiation phase of protein synthesis is governed by the presence of initiation factors that guide the transition of the small ribosomal subunit (30S) from an unlocked preinitiation complex (30S preIC) to a locked initiation ...

Ribosome•RelA structures reveal the mechanism of stringent response activation

eLife, 2016
Stringent response is a conserved bacterial stress response underlying virulence and antibiotic resistance. RelA/SpoT-homolog proteins synthesize transcriptional modulators (p)ppGpp, allowing bacteria to adapt to stress.
