• membrane-bound receptors interact strongly with short peptidic segments of a larger protein chain, for example, recognition of the RGD sequence (arginine–glycine–aspartic acid; Arg–Gly–Asp) by integrin receptors. They use noncovalent interactions including salt bridges [5]. Vancomycin, a glycopeptide

• antibiotic, is used for the treatment of resistant bacterial infections. Its interaction with a small peptidic segment of the bacteria cell wall is a classic example of molecular recognition [6][7]. Peptides are often substrates for protease enzymes [8][9]. Enzymologists have studied the chemical principles
