Distinct profiling of antimicrobial peptide families
2014
Computer applications in the biosciences : CABIOS
Preserved Fulltext
Antimicrobial peptides (AMPs) exhibit broad-spectrum potent activity against MDR pathogens and kills rapidly, thus giving rise to AMPs being recognized as a potential substitute for conventional antibiotics ...
Motivation: The increased prevalence of multi-drug resistant (MDR) pathogens heightens the need to design new antimicrobial agents. ...
This Profiling of antimicrobial peptide families suggests that the features selected based on DAMPD entries discriminate well between different AMP families in the CAMP database. ...
