How innate immunity proteins kill bacteria and why they are not prone to resistance [PDF]
, 2017 Recent advances on antibacterial activity of peptidoglycan recognition proteins (PGRPs) offer some insight into how innate immunity has retained its antimicrobial effectiveness for millions of years with no frequent emergence of resistant strains. First,

Advanced Healthcare Materials, EarlyView.By fusing ACE2‐overexpressing membrane‐integrated liposome (MIL) with copper nanoparticles, the biomimetic Cu@MIL nanostructures were created that directly hijack the SARS‐CoV‐2 entry pathway. These particles combine potent virus‐targeting precision with intrinsic antiviral activity, achieving rapid neutralization and disinfection.

Structural basis for Fe-S cluster assembly and tRNA thiolation mediated by IscS protein-protein interactions. [PDF]
PLoS Biology, 2010 The cysteine desulfurase IscS is a highly conserved master enzyme initiating sulfur transfer via persulfide to a range of acceptor proteins involved in Fe-S cluster assembly, tRNA modifications, and sulfur-containing cofactor biosynthesis.

Maintenance of genome integrity by the late-acting cytoplasmic iron-sulfur assembly (CIA) complex
Frontiers in Genetics, 2023 Iron-sulfur (Fe-S) clusters are unique, redox-active co-factors ubiquitous throughout cellular metabolism. Fe-S cluster synthesis, trafficking, and coordination result from highly coordinated, evolutionarily conserved biosynthetic processes.
