However, the rest of the protein adopts an Alpha-helical conformation between residues 15 and 36 with a kink or hinge at 25-27. The pH-dependent unfolding to a random coil conformation precedes any tendency of this peptide to aggregate to a Beta-sheet as the pH increases.", "ec_number": "", "global_stoichiometry": "Monomer - A ", "ligand_name": "", "ligand_id": "", "pdb_classification": "GLYCOPROTEIN", "length": "40", "keyword": "AMYLOID BETA-PEPTIDE", "amyloid_non_amyloid": "Amyloid", "inchi": "", "reference": "Biochemistry. 1998 Aug 4;37(31):11064-77", "alternative_name": "ABPP, APPI, Alzheimer disease amyloid protein, Amyloid precursor protein, Amyloid-beta precursor protein, Cerebral vascular amyloid peptide, PreA4, Protease nexin-II", "ligand_smiles": "", "inchi_key": ""}
