Proline In Polypeptide Chain
Proline In Polypeptide Chain . The conformational restrictions imposed by proline motifs in a peptide chain appear to imply important structural or biological functions as can be deduced from their often. The extended conformation of ppii helices precludes the formation of intramolecular interactions between side chains. PPT CHAPTER 4 Proteins Structure, Function, Folding PowerPoint from www.slideserve.com A series of amino acids that are joined together in a specific sequence. The structure of a polypeptide chain is a linear sequence of amino acids. The main chain of proline residues has a restricted conformational space with a far smaller range of allowed phi/psi angles than other amino acid have.
