KR-12–Cu(II) Binding: Theory Meets Experiment
2026-09-12
The reference study combines GFN2-xTB/ALPB calculations with potentiometric titration and isothermal titration calorimetry to clarify how the antimicrobial KR-12 peptide coordinates Cu(II). Its main contribution is a chemically resolved interpretation showing that backbone oxygen atoms dominate favorable binding modes, while aspartate and Arg29 strongly influence the interaction.

Carbapenemase Gene Transmission in CREC
2026-09-08
This 2025 BMC Microbiology study maps carbapenemase-encoding genes in carbapenem-resistant Enterobacter cloacae across eight teaching hospitals in Guangdong. Its combination of gene-localization, conjugation, mobile-element, susceptibility, and strain-typing analyses shows that blaNDM-1 is frequently plasmid-associated and readily transferable, providing a practical framework for antimicrobial resistance research.

BicD and MAP7 Activate Drosophila Kinesin-1
2026-09-08
Ali et al. show that BicD and MAP7 activate homodimeric Drosophila kinesin-1 through distinct but complementary mechanisms. BicD primarily relieves kinesin autoinhibition, whereas MAP7 improves microtubule recruitment and extends movement, producing the strongest activation when both factors are present.
