TTR is a transporter of thyroxine and retinol in the blood and cerebrospinal fluid. When mutated and/or as a result of aging, TTR aggregates into amyloid fibrils that accumulate in organs such as the heart. The segments from the C-terminal region of TTR form in-register steric-zippers with highly-interdigitated, wet interfaces, whereas the Beta-strand B from the N-terminal region of TTR forms an out-of-register assembly, previously associated with oligomeric formation.", "ligstr": "SO4:A:O4 S -2:96.06:SULFATE ION:[O-]S(=O)(=O)[O-]:InChI=1S/H2O4S/c1-5(2,3)4/h(H2,1,2,3,4)/p-2:QAOWNCQODCNURD-UHFFFAOYSA-L;GOL:B:C3 H8 O3:92.09:GLYCEROL:C(C(CO)O)O:InChI=1S/C3H8O3/c4-1-3(6)2-5/h3-6H,1-2H2:PEDCQBHIVMGVHV-UHFFFAOYSA-N", "pmid": "29626847", "remarks": "AMYLOID FORMING PEPTIDE KALGIS FROM TRANSTHYRETIN", "amyloid_non_amyloid": "Amyloid", "type": "Fibril", "inchi": "InChI=1S/H2O4S/c1-5(2,3)4/h(H2,1,2,3,4)/p-2%%InChI=1S/C3H8O3/c4-1-3(6)2-5/h3-6H,1-2H2", "resolution": "1.6", "species": "Homo sapiens", "secondary_structure": "KALGIS#CCEEEC&KALGIS#CCEEEC", "chain_id": "A%%B", "gene_names": "", "r_value_free": "0.212", "pdb_id": "6C3G", "reference": "Protein Sci. 2018 Jul;27(7):1295-1303.", "keyword": "LYS-ALA-LEU-GLY-ILE-SER", "protein_name": "Transthyretin", "ligand_formula": "O4 S -2%%C3 H8 O3", "peptide_protein_sequence": "chain-ID A: KALGIS; chain-ID B: KALGIS", "entry": "S-0510", "length": "6", "uniprot_ac": "", "author": "Saelices, L., Sievers, S.A., Sawaya, M.R., Eisenberg, D.S.", "ligand_smiles": "[O-]S(=O)(=O)[O-]%%C(C(CO)O)O", "ligand_mw": "96.06%%92.09", "alternative_name": "", "ligand_name": "SULFATE ION%%GLYCEROL", "pdb_classification": "PROTEIN FIBRIL", "global_stoichiometry": "Homo 20-mer - A20 ", "inchi_key": "QAOWNCQODCNURD-UHFFFAOYSA-L%%PEDCQBHIVMGVHV-UHFFFAOYSA-N", "ligand_id": "SO4%%GOL"}
