Native contact density and nonnative hydrophobic effects in the folding of bacterial immunity proteins. [PDF]

open access: yesPLoS Computational Biology, 2015
The bacterial colicin-immunity proteins Im7 and Im9 fold by different mechanisms. Experimentally, at pH 7.0 and 10°C, Im7 folds in a three-state manner via an intermediate but Im9 folding is two-state-like.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Resonance-Driven Passive Folding/Unfolding Flapping Wing Actuator

open access: yesApplied Sciences, 2020
The wings of flapping-wing micro aerial vehicles (MAVs) face the risk of breakage. To solve this issue, we propose the use of a biomimetic foldable wing.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Protein folding in silico : protein folding versus protein structure prediction / [PDF]

open access: yes, 2012
Protein folding is a process by which a protein structure assumes its functional shape of conformation, and has been the subject of research since the publication of the first software tool for protein structure prediction.

Folding of the transcription factor Brinker and interactions of the bacterial second messenger c-di-GMP studied by NMR [PDF]

open access: yes, 2013
Nuclear magnetic resonance (NMR) spectroscopy is a technique, which allows the non-invasive investigation of structures, dynamics and interactions of biomolecules.

Unfolding Crease Patterns Inspired by Insect Wings and Variations of the Miura-ori with a Single Vein

open access: yesBiomimetics, 2019
In many disciplines, professionals are interested in folding patterns for their packing and shape changing capabilities. Many insects have folded wings fitting to their body morphology that can unfold to fly, support their weight and withstand external ...

BiP clustering facilitates protein folding in the endoplasmic reticulum. [PDF]

open access: yesPLoS Computational Biology, 2014
The chaperone BiP participates in several regulatory processes within the endoplasmic reticulum (ER): translocation, protein folding, and ER-associated degradation. To facilitate protein folding, a cooperative mechanism known as entropic pulling has been
