Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Spiral Structure Properties, Dynamics, and Evolution in Milky Way–mass Galaxy Simulations

The Astrophysical Journal
The structure of spiral galaxies is essential to understanding the dynamics and evolution of disk galaxies; however, the precise nature of spiral arms remains uncertain.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Bottom’s Dream and the Amplification of Filamentary Gas Structures and Stellar Spiral Arms

The Astrophysical Journal
Theories of spiral structure traditionally separate into tight-winding Lin–Shu spiral density waves and the swing-amplified material patterns of Goldreich & Lynden-Bell and Julian & Toomre.

Shear behavior of GFRP spiral reinforced concrete beams

Results in Engineering
Corrosion of steel reinforcement remains a critical durability concern in reinforced concrete (RC) structures, motivating the adoption of fiber-reinforced polymers (FRP) as non-corrosive alternatives. This study explores the use of glass fiber-reinforced

Simulation of Quality Death Spirals based on Human Resources Dynamics

Inquiry: The Journal of Health Care Organization, Provision, and Financing, 2019
Although the hospital managers always try to improve the quality of the medical services, sometimes their efforts might affect reversely and push the system in what is so commonly called as “the death spirals of quality.” The most important reason of ...
