THE 2.9 ANGSTROM CRYSTAL STRUCTURE CONFIRMS THAT THE PROTEIN IS A FOUR HELIX BUNDLE, AS IT WAS DESIGNED TO BE. THE COMPLETE 108 RESIDUE SEQUENCE IS PRESENTED ON SEQRES RECORDS BELOW. THE HELICES WERE CONNECTED BY LOOPS OF 3, 4, 3 GLYCINES, RESPECTIVELY. THE MOLECULE CONTAINS A CRYSTALLOGRAPHIC TW0-FOLD AXIS OF SYMMETRY THROUGH THE CENTER OF THE 4-HELIX BUNDLE. THIS UNUSUAL ARRANGEMENT IS DUE TO THE SYNTHETIC NATURE OF THE MOLECULE IN WHICH THE SAME SEQUENCE SEGMENTS REPEAT. THE SYMMETRY OPERATION REQUIRED TO GENERATE THE ENTIRE BUNDLE IS (-Y+1, -X+1, 1/3-Z) AND IS GIVEN IN REMARK 350 AS AN OPERATOR ON THE COORDINATES IN THIS ENTRY. ; 2 non-polymer syn 'UNKNOWN ATOM OR ION' ? 2 ? ? ? ? 3 water nat water 18.015 2 ? ? ? ? # _entity_poly.entity_id 1 _entity_poly.type 'polypeptide(L)' _entity_poly.nstd_linkage no _entity_poly.nstd_monomer no _entity_poly.pdbx_seq_one_letter_code ;SSEELLKQALQQAQQLLQQAQELAKKGGGEELLKQALQQAQQLLQQAQELAKKGGGGEELLKQALQQAQQLLQQAQELAK KGGGEELLKQALQQAQQLLQQAQELAKK ; _entity_poly.pdbx_seq_one_letter_code_can ;SSEELLKQALQQAQQLLQQAQELAKKGGGEELLKQALQQAQQLLQQAQELAKKGGGGEELLKQALQQAQQLLQQAQELAK KGGGEELLKQALQQAQQLLQQAQELAKK ; _entity_poly.pdbx_strand_id A _entity_poly.pdbx_target_identifier ? # loop_ _pdbx_entity_nonpoly.entity_id _pdbx_entity_nonpoly.name _pdbx_entity_nonpoly.comp_id 2 'UNKNOWN ATOM OR ION' UNX 3 water HOH # loop_ _entity_poly_seq.entity_id _entity_poly_seq.num _entity_poly_seq.mon_id _entity_poly_seq.hetero 1 1 SER n 1 2 SER n 1 3 GLU n 1 4 GLU n 1 5 LEU n 1 6 LEU n 1 7 LYS n 1 8 GLN n 1 9 ALA n 1 10 LEU n 1 11 GLN n 1 12 GLN n 1 13 ALA n 1 14 GLN n 1 15 GLN n 1 16 LEU n 1 17 LEU n 1 18 GLN n 1 19 GLN n 1 20 ALA n 1 21 GLN n 1 22 GLU n 1 23 LEU n 1 24 ALA n 1 25 LYS n 1 26 LYS n 1 27 GLY n 1 28 GLY n 1 29 GLY n 1 30 GLU n 1 31 GLU n 1 32 LEU n 1 33 LEU n 1 34 LYS n 1 35 GLN n 1 36 ALA n 1 37 LEU n 1 38 GLN n 1 39 GLN n 1 40 ALA n 1 41 GLN n 1 42 GLN n 1 43 LEU n 1 44 LEU n 1 45 GLN n 1 46 GLN n 1 47 ALA n 1 48 GLN n 1 49 GLU n 1 50 LEU n 1 51 ALA n 1 52 LYS n 1 53 LYS n 1 54 GLY n 1 55 GLY n 1 56 GLY n 1 57 GLY n 1 58 GLU n 1 59 GLU n 1 60 LEU n 1 61 LEU n 1 62 LYS n 1 63 GLN n 1 64 ALA n 1 65 LEU n 1 66 GLN n 1 67 GLN n 1 68 ALA n 1 69 GLN n 1 70 GLN n 1 71 LEU n 1 72 LEU n 1 73 GLN n 1 74 GLN n 1 75 ALA n 1 76 GLN n 1 77 GLU n 1 78 LEU n 1 79 ALA n 1 80 LYS n 1 81 LYS n 1 82 GLY n 1 83 GLY n 1 84 GLY n 1 85 GLU n 1 86 GLU n 1 87 LEU n 1 88 LEU n 1 89 LYS n 1 90 GLN n 1 91 ALA n 1 92 LEU n 1 93 GLN n 1 94 GLN n 1 95 ALA n 1 96 GLN n 1 97 GLN n 1 98 LEU n 1 99 LEU n 1 100 GLN n 1 101 GLN n 1 102 ALA n 1 103 GLN n 1 104 GLU n 1 105 LEU n 1 106 ALA n 1 107 LYS n 1 108 LYS n # _entity_src_gen.entity_id 1 _entity_src_gen.pdbx_src_id 1 _entity_src_gen.pdbx_alt_source_flag sample _entity_src_gen.pdbx_seq_type ? _entity_src_gen.pdbx_beg_seq_num ? _entity_src_gen.pdbx_end_seq_num ? _entity_src_gen.gene_src_common_name ? _entity_src_gen.gene_src_genus ? _entity_src_gen.pdbx_gene_src_gene 'SYNTHETIC GENE DHP1' _entity_src_gen.gene_src_species ? _entity_src_gen.gene_src_strain ? _entity_src_gen.gene_src_tissue ? _entity_src_gen.gene_src_tissue_fraction ? _entity_src_gen.gene_src_details ? _entity_src_gen.pdbx_gene_src_fragment ? _entity_src_gen.pdbx_gene_src_scientific_name 'synthetic construct' _entity_src_gen.pdbx_gene_src_ncbi_taxonomy_id 32630 _entity_src_gen.pdbx_gene_src_variant ? _entity_src_gen.pdbx_gene_src_cell_line ? _entity_src_gen.pdbx_gene_src_atcc ? _entity_src_gen.pdbx_gene_src_organ ? _entity_src_gen.pdbx_gene_src_organelle ? _entity_src_gen.pdbx_gene_src_cell ? _entity_src_gen.pdbx_gene_src_cellular_location ? _entity_src_gen.host_org_common_name ? _entity_src_gen.pdbx_host_org_scientific_name 'Escherichia coli' _entity_src_gen.pdbx_host_org_ncbi_taxonomy_id 562 _entity_src_gen.host_org_genus Escherichia _entity_src_gen.pdbx_host_org_gene 'SYNTHETIC GENE DHP1' _entity_src_gen.pdbx_host_org_organ ? _entity_src_gen.host_org_species ? _entity_src_gen.pdbx_host_org_tissue ? _entity_src_gen.pdbx_host_org_tissue_fraction ? _entity_src_gen.pdbx_host_org_strain XL1-BLUE _entity_src_gen.pdbx_host_org_variant ? _entity_src_gen.pdbx_host_org_cell_line ? _entity_src_gen.pdbx_host_org_atcc ? _entity_src_gen.pdbx_host_org_culture_collection ? _entity_src_gen.pdbx_host_org_cell ? _entity_src_gen.pdbx_host_org_organelle ? _entity_src_gen.pdbx_host_org_cellular_location ? _entity_src_gen.pdbx_host_org_vector_type ? _entity_src_gen.pdbx_host_org_vector ? _entity_src_gen.host_org_details ? _entity_src_gen.expression_system_id ? _entity_src_gen.plasmid_name PMAL-C2 _entity_src_gen.plasmid_details ? _entity_src_gen.pdbx_description 'DE NOVO DESIGNED FOUR HELIX BUNDLE PROTEIN' # loop_ _chem_comp.id _chem_comp.type _chem_comp.mon_nstd_flag _chem_comp.name _chem_comp.pdbx_synonyms _chem_comp.formula _chem_comp.formula_weight ALA 'L-peptide linking' y ALANINE ?
