An isopeptide bond is a type of covalent bond that forms between the carboxyl group of one amino acid and the amino group of another amino acid, specifically when the bond occurs between the side chain of one amino acid (usually one possessing a reactive group such as lysine or aspartic acid) and the backbone or side chain of another amino acid.
