WebbAntimicrobial peptides (AMPs) represent a skilled class of new antibiotics, due to their broad range of activity, rapid killing, and low bacterial resistance. Many efforts have been made to discover AMPs with improved performances, i.e., high antimicrobial activity, low cytotoxicity against human cells, stability against proteolytic degradation, and low costs … WebbThe local organization of a protein's polypeptide backbone, which is composed of repeating units of the amino acids connected by peptide bonds, is known as the secondary structure. The consistent folding patterns that are supported by hydrogen bonds between the amino acids in the core of a polypeptide define this level of organization.
