THE RESULT IS A POLYMER-LIKE STRUCTURE WITH NO DEFINED ENDS. THE POLYMER STRUCTURE IS FORMED BY CONTINUATION OF THE CHAINS USING THE SYMMETRY-RELATED MOLECULES ALONG THE HELICAL AXIS. THE TVECT RECORD BELOW PRESENTS THE TRANSLATION THAT WILL GENERATE THE POLYMER. NOTE: THEREFORE, CLOSE CONTACTS BETWEEN SYMMETRY-RELATED MOLECULES ARE INTENTIONAL AND NECESSARY. INTERCHAIN HYDROGEN BONDING AT THE END OF CHAINS ALSO UTILIZES SYMMETRY-RELATED MOLECULES. THE ENTIRE 30 RESIDUE LONG PEPTIDE CAN BE GENERATED FROM THE SUBMITTED ASYMMETRIC UNIT BY APPLYING THE FOLLOWING TRANSLATIONS (USING FRACTIONAL COORDINATES): CHAIN A: TRANSLATE RESIDUES 1 - 9 BY (0 0 1), (0 0 2), AND (0 0 3) AND RESIDUES 7 - 9 BY (0 0 4). CHAIN B: TRANSLATE RESIDUES 31 - 36 BY (0 0 1), (0 0 2), AND (0 0 3). CHAIN C: TRANSLATE RESIDUES 61 - 66 BY (0 0 1), (0 0 2), AND (0 0 3) AND RESIDUES 64 - 66 BY (004). THIS WILL RESULT IN A MOLECULE WITH A TOTAL OF 90 RESIDUES, 30 IN EACH CHAIN. ; _struct_biol.pdbx_parent_biol_id ? # loop_ _struct_conn.id _struct_conn.conn_type_id _struct_conn.pdbx_leaving_atom_flag _struct_conn.pdbx_PDB_id _struct_conn.ptnr1_label_asym_id _struct_conn.ptnr1_label_comp_id _struct_conn.ptnr1_label_seq_id _struct_conn.ptnr1_label_atom_id _struct_conn.pdbx_ptnr1_label_alt_id _struct_conn.pdbx_ptnr1_PDB_ins_code _struct_conn.pdbx_ptnr1_standard_comp_id _struct_conn.ptnr1_symmetry _struct_conn.ptnr2_label_asym_id _struct_conn.ptnr2_label_comp_id _struct_conn.ptnr2_label_seq_id _struct_conn.ptnr2_label_atom_id _struct_conn.pdbx_ptnr2_label_alt_id _struct_conn.pdbx_ptnr2_PDB_ins_code _struct_conn.ptnr1_auth_asym_id _struct_conn.ptnr1_auth_comp_id _struct_conn.ptnr1_auth_seq_id _struct_conn.ptnr2_auth_asym_id _struct_conn.ptnr2_auth_comp_id _struct_conn.ptnr2_auth_seq_id _struct_conn.ptnr2_symmetry _struct_conn.pdbx_ptnr3_label_atom_id _struct_conn.pdbx_ptnr3_label_seq_id _struct_conn.pdbx_ptnr3_label_comp_id _struct_conn.pdbx_ptnr3_label_asym_id _struct_conn.pdbx_ptnr3_label_alt_id _struct_conn.pdbx_ptnr3_PDB_ins_code _struct_conn.details _struct_conn.pdbx_dist_value _struct_conn.pdbx_value_order _struct_conn.pdbx_role covale1 covale both ?
