41. The other two dihedral angles in the peptide bond determine the local shape assumed by the protein backbone. 42. A simple example is the condensation of two amino acids to form the peptide bond characteristic of proteins. 43. This exposes the protein's peptide bonds . 44. The subunit is circularized by the formation of a peptide bond between the two ends of the polypeptide. 45. Isomerization of an X-Pro peptide bond . 46. At higher temperatures ( 37 to 60 �C ), peptide bonds assist in the formation of the reaction complex. 47. The cleavage of peptide bonds by OmpT is also dependent on the presence of bound lipopolysaccharide ( LPS ). 48. Upon addition of sortase to the protein mixture, the two peptides are covalently linked through a native peptide bond . 49. It showed, however, that had amino acids formed under these conditions, they could go on to form peptide bonds . 50. The peptide bond cleavage occurs via the nucleophilic attack of water at the carbonyl between two adjacent amino acid residues.
