Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Single-molecule fluorescence studies of Protein Folding and Molecular Chaperones [PDF]

open access: yes, 2011
Folding of newly synthesized proteins is an essential part of protein biosynthesis and misfolding can result in protein aggregation which can also lead to several severe diseases.

Protein folding disorders: Toward a basic biological paradigm

open access: yes, 2010
Mechanistic 'physics' models of protein folding fail to account for the observed spectrum of protein folding and aggregation disorders, suggesting that a more appropriately biological paradigm will be needed for understanding the etiology ...

Single time-point analysis of product and substrate inhibition

open access: yesScientific Reports
When enzyme inhibition by either the product or excess substrate occurs, it is possible to determine the characteristic kinetic parameters based on [P]/t measurements, even when a large proportion of the substrate is converted.

Trans-translation exposed: understanding the structures and functions of tmRNA-SmpB

open access: yesFrontiers in Microbiology, 2014
Ribosome stalling is a serious issue for cell survival. In bacteria, the primary rescue system is trans-translation, performed by tmRNA and its protein partner small protein B (SmpB).

SFRS-Net: A Cloud-Detection Method Based on Deep Convolutional Neural Networks for GF-1 Remote-Sensing Images

open access: yesRemote Sensing, 2021
Clouds constitute a major obstacle to the application of optical remote-sensing images as they destroy the continuity of the ground information in the images and reduce their utilization rate.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Without magic bullets: the biological basis for public health interventions against protein folding disorders

open access: yes, 2010
Protein folding disorders of aging like Alzheimer's and Parkinson's diseases currently present intractable medical challenges. 'Small molecule' interventions - drug treatments - often have, at best, palliative impact, failing to alter

Minimal Retraction of Space-time and Their Foldings [PDF]

open access: yes, 2009
The folding of a manifold was, firstly introduced by Robertson in [1977] . Since then many authers have studied the folding of manifolds s. The deformation retracts of the manifolds defined and discussed.
