Proline and glycine play common roles in turns, providing less flexibility (starting the turn ... federal bank school fee paymentThe distinctive cyclic structure of proline's side chain gives proline an exceptional conformational rigidity compared to other amino acids. It also affects the rate of peptide bond formation between proline and other amino acids. When proline is bound as an amide in a peptide bond, its nitrogen is not bound to any hydrogen, meaning it cannot act as a hydrogen bond donor, but can be a hydrogen bond acceptor. federal bank scholarship 2021-22WebApr 19, 2010 · Proline residues facilitate the formation of protein secondary structure elements such as turns and the polyproline II helix, but typically disfavour α helix and β-strand conformations.
