D-Stereoselective peptidases that degrade non-ribosomal peptides (NRPs) were recently discovered and could have serious implications for the future of NRPs as antibiotics. Herein, we report chemical modifications that can be used to impart re-sistance to the D-peptidases BogQ and TriF. New tridecaptin A analogues were synthesized that retain strong antimicrobial activity and have significantly enhanced D-peptidase stability. In vitro assays confirmed that synthetic analogues retain the ability to bind to their cellular receptor, peptidoglycan intermediate lipid II.
FingerprintDive into the research topics of 'A Chemical-Intervention Strategy to Circumvent Peptide Hydrolysis by D-Stereoselective Peptidases'. Together they form a unique fingerprint.
