Genome-wide Translation Profiling by Ribosome-Bound tRNA Capture

open access: yesCell Reports, 2018
Summary: In the ribosome complex, tRNA is a critical element of mRNA translation. A rich repertoire of cell regulation is hypothesized to occur during the recruitment of specific tRNAs in polypeptide formation.

A New Function for Amyloid-Like Interactions: Cross-Beta Aggregates of Adhesins form Cell-to-Cell Bonds

open access: yesPathogens, 2021
Amyloid structures assemble through a repeating type of bonding called “cross-β”, in which identical sequences in many protein molecules form β-sheets that interdigitate through side chain interactions.

Conformational kinetics reveals affinities of protein conformational states [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance Despite 50 years of studies of coupled binding and conformational change reactions in proteins and nucleic acids, there has been no detailed analysis of the affinities of the multiple conformational states involved. The relationship between these affinities and the dynamics of conformational change has also been largely ...

Infrared spectroscopy analysis determining secondary structure change in albumin by cerium oxide nanoparticles

open access: yesFrontiers in Toxicology, 2023
Cerium oxide (CeO2) nanoparticles are expected to have applications in the biomedical field because of their antioxidative properties. Inorganic nanoparticles interact with proteins at the nanoparticle surface and change their conformation when ...

Aβ Secretion and Plaque Formation Depend on Autophagy

open access: yesCell Reports, 2013
Alzheimer’s disease (AD) is a neurodegenerative disease biochemically characterized by aberrant protein aggregation, including amyloid beta (Aβ) peptide accumulation. Protein aggregates in the cell are cleared by autophagy, a mechanism impaired in AD. To

Limited proteolysis in the investigation of beta2-microglobulin amyloidogenic and fibrillar states. [PDF]

open access: yes, 2005
Amyloid fibrils of patients treated with regular haemodialysis essentially consists of β2-microglobulin (β2-m) and its truncated species ΔN6β2-m lacking six residues at the amino terminus.

Cooperative Gating and Spatial Organization of Membrane Proteins through Elastic Interactions [PDF]

open access: yes, 2007
Biological membranes are elastic media in which the presence of a transmembrane protein leads to local bilayer deformation. The energetics of deformation allow two membrane proteins in close proximity to influence each other's equilibrium conformation ...

Coupling of a Microfluidic Mixer to a Fourier-transform Infrared Spectrometer for Protein-Conformation Studies

open access: yesCHIMIA, 2011
The biological properties of a protein critically depend on its conformation, which can vary as a result of changes in conditions such as pH or following the addition of various substances.

Sequence-Dependent Correlated Segments in the Intrinsically Disordered Region of ChiZ

open access: yesBiomolecules, 2020
How sequences of intrinsically disordered proteins (IDPs) code for their conformational dynamics is poorly understood. Here, we combined NMR spectroscopy, small-angle X-ray scattering (SAXS), and molecular dynamics (MD) simulations to characterize the ...
