Abstract in brief

The study focuses on developing improved proline-rich antimicrobial peptides (PrAMPs), specifically derivatives of Bac5117, to fight multidrug-resistant bacteria like E. coli, K. pneumoniae, and A. baumannii, by modifying their amino acid sequences.
Researchers identified critical motifs in Bac5117 that must remain unchanged and others that can be varied, leading to the creation of five new peptides with more arginine and tryptophan residues, which showed enhanced antimicrobial effects without increasing toxicity to human cells.
These new peptides exhibit a dual mechanism of action—both inhibiting bacterial protein synthesis and disrupting bacterial membranes—potentially reducing the likelihood of bacteria developing resistance.]
