Designing of a penta-peptide against drug resistant E. coli

Drug resistant pathogens are vibrant global problem. Penicillin binding protein 5 (PBP5) plays important role in bacterial cell wall biosynthesis. Mutation in PBP5 is a well-known mechanism for development of drug resistant strain of bacteria. In this context we have designed a peptide that fits better at the ligand-binding site of mutant PBP5 compared to wild type PBP5. It is expected that the designed peptide will halt the growth of drug resistant pathogen harboring mutant variety of PBP5. We have recommended experimental validation of the above concept.
