Chemoproteomics Unveils the Antibacterial Mechanism of Silver Ions: Inhibiting Peptidoglycan Synthesis via Targeting Mur Family Proteins in Staphylococcus aureus
Key Points
This research aims to clarify the antibacterial mechanism of silver ions, particularly their action against Staphylococcus aureus.
Utilized chemoproteomics to investigate the mechanism of action.
Analyzed the impact of silver ions on peptidoglycan synthesis.
Focused on the activity against Mur family proteins in Staphylococcus aureus.
Silver ions demonstrated strong antibacterial activity against Staphylococcus aureus.
Inhibition of peptidoglycan synthesis was confirmed.
Targeting of Mur family proteins was established as a key mechanism.
Abstract
Silver ions (Ag+) have long been employed as natural antimicrobial agents, yet their precise mechanism of action remains unclear. In this study, we show that Ag++ displays strong antibacterial activity...
