Microcin J25 (MccJ25) is a small ribosomally synthesized antimicrobial peptide that is produced by Enterobacteriacea family especially E.coli. The present study focuses on preparation and evaluation of in vitro antimicrobial and biological properties of a new peptide derived from MccJ25. We prepared a MccJ25-derived peptide containing 14 amino acids and a single intra-molecular disulfide bond a...
