Folding of Protein L with implications for collapse in the denatured state ensemble [PDF]

open access: yes, 2016
A fundamental question in protein folding is whether the coil to globule collapse transition occurs during the initial stages of folding (burst-phase) or simultaneously with the protein folding transition. Single molecule fluorescence resonance energy transfer (FRET) and small angle X-ray scattering (SAXS) experiments disagree on whether Protein L ...

Two State Behavior in a Solvable Model of $\beta$-hairpin folding

open access: yes, 1999
Understanding the mechanism of protein secondary structure formation is an essential part of protein-folding puzzle. Here we describe a simple model for the formation of the $\beta$-hairpin, motivated by the fact that folding of a $\beta$-hairpin ...

Chaperones and protein folding

open access: yesCurrent Opinion in Cell Biology, 1992
Chaperones are centrally involved in the control of protein structure, function, localization and transport. A flurry of scientific activity continues to examine the molecular nature of chaperone-substrate recognition and the role of auxiliary chaperones (cohort proteins) and small molecules that expedite these processes.

Protein Folding and Mechanisms of Proteostasis

open access: yesInternational Journal of Molecular Sciences, 2015
Highly sophisticated mechanisms that modulate protein structure and function, which involve synthesis and degradation, have evolved to maintain cellular homeostasis. Perturbations in these mechanisms can lead to protein dysfunction as well as deleterious

Disruption of SETD3‐mediated histidine‐73 methylation by the BWCFF‐associated β‐actin G74S mutation

open access: yesFEBS Letters, EarlyView.
The β‐actin G74S mutation causes altered interaction of actin with SETD3, reducing histidine‐73 methylation efficiency and forming two distinct actin variants. The variable ratio of these variants across cell types and developmental stages contributes to tissue‐specific phenotypical changes. This imbalance may impair actin dynamics and mechanosensitive

Application of a Dual Internally Quenched Fluorogenic Substrate in Screening for D-Arginine Specific Proteases

open access: yesFrontiers in Microbiology, 2019
The application of D-stereospecific proteases (DSPs) in resolution of racemic amino acids and in the semisynthesis of proteins has been a successful strategy.

Electrostatic Interactions in Protein Structure, Folding, Binding, and Condensation.

open access: yesChemical Reviews, 2018
Charged and polar groups, through forming ion pairs, hydrogen bonds, and other less specific electrostatic interactions, impart important properties to proteins.

Flow‐based immunomagnetic enrichment of circulating tumor cells from diagnostic leukapheresis product

open access: yesMolecular Oncology, EarlyView.
The number of circulating tumor cells obtained from prostate cancer patients was increased approximately 5‐fold compared to regular CellSearch when processing 2 mL diagnostic leukapheresis material aliquots and increased by 44‐fold when processing 20 mL DLA aliquots using the flow enrichment target capture Halbach‐array.

Pharmacological chaperone reshapes the energy landscape for folding and aggregation of the prion protein

open access: yesNature Communications, 2016
Small-molecule chaperones that can prevent protein misfolding have potential applications for treating diseases such as Alzheimer’s and ALS. Here the authors use high-resolution force spectroscopy to gain insight into the mechanism of action of an iron ...
