In the bacterium M. smegmatis, an enzyme called MftG allows the cofactor mycofactocin to transfer electrons released during ethanol metabolism to the electron transport chain.
A combination of polymer physics theories consistently rationalizes comprehensive experimental effects of salt, ATP, phosphorylation, and sequence charge and arginine/lysine patterns on the reentrant phase behaviors of intrinsically disordered proteins.

Computational modeling and in vitro experiments identify a unique conformational state in amyloidogenic light chains, providing a structural basis for amyloidosis and a precise target for drug design.
The buildup of knot-like RNA structures in brain cells may be the key to understanding how uncontrolled protein aggregation drives Alzheimer’s disease.

A deep mutational scan of MET kinase domain variants reveals resistance and sensitizing mutations for 11 inhibitors, providing a mutation-specific reference for precision therapies and drug development.
SERBP1 is associate with protein complexes regulating splicing, cell division, and ribosomal biogenesis that likely depend on G quadruplex (G4) binding and polyADP-ribosylation (PARylation) for their assembly and function.
Further evidence in support of a new amyloid-independent hypothesis for the pathogenesis of Alzheimer's disease is provided, with an expanded set of Alzheimer-causing mutations in the protease that produces amyloid.
