Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Structural Differences Between Amyloid Beta Oligomers [PDF]
In Alzheimer’s disease, soluble Aβ oligomers are believed to play important roles in the disease pathogenesis, and their levels correlate with cognitive impairment.

Heterotropic regulation and negative homotropic cooperativity
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Probing High-Order Transient Oligomers using Ion Mobility Mass Spectrometry coupled to Infrared Action Spectroscopy [PDF]
Understanding and controlling peptide aggregation is critical due to its neurotoxic implications. However, structural information on the key intermediates, the oligomers, is obscured by a cascade of coinciding events occurring at various time and energy ...

Crystalline assemblies of folded oligomers [PDF]
In this work a novel design concept for folded oligomers is presented. The concept involves the insertion of a rigid spacer, the 1,3-bis(ethynylene)benzene unit, into linear alkyl-chain oligomers.

The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Single-stranded DNA binding proteins (SSBs) bind to single-stranded DNA in a sequence-independent manner to prevent formation of secondary structures and protect DNA from nuclease degradation.

A mimotope of A beta oligomers may also behave as a beta-sheet inhibitor
Beta-amyloid (A beta) oligomers are strongly associated with the cascade of harmful events leading to neurodegeneration in Alzheimer's disease (AD). Elimination of A beta oligomers or inhibition of A beta assembly is a valuable therapeutic approach

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

MARK4 enhances stress granule formation under oxidative stress and increases tau accumulation
MARK4 (red dots) localizes to stress granules (orange dots) and promotes their formation under oxidative stress by modulating TIA1 (blue dots). MARK4 and TIA1 synergistically increase tau (purple) accumulation, and the reduction of the TIA1 ortholog suppresses neurodegeneration in a fly model.
