THE CRYSTALS WERE GROWN FROM TWO 18MER OLIGORIBONUCLEOTIDES, WITH SEQUENCES 5'-R(*CP*AP*CP*CP*GP*UP*UP*GP*GP*UP*AP*GP* CP*GP*GP*UP*GP*C)-3' AND 5'-R(*CP*AP*CP*CP*GP*CP*UP*AP*CP* CP*AP*AP*CP*GP*GP*UP*GP*C)-3' RESPECTIVELY. THESE SEQUENCES OCCUR NATURALLY IN E. COLI. THE AVERAGING PRODUCES CRYSTALS WITH ONE TURN, 11 BASE PAIRS, OF A RNA IN THE ASYMMETRIC UNIT. THIS IS MODELED USING ONE G AND ONE C RESIDUE CONNECTED TO EACH RIBOSE C1*, WITH PARTIAL OCCUPANCIES EQUAL TO THE FREQUENCIES OF PURINES AND PYRIMIDINES, RESPECTIVELY, IN THE 18MER DUPLEX. STRAND A, ALL G'S, AND STRAND C, ALL C'S, HAVE IDENTICAL RIBOSE AND PHOSPHATE COORDINATES AND ATOMIC DISPLACEMENT PARAMETERS; LIKEWISE STRAND B, ALL C'S, AND STRAND D, ALL G'S, HAVE IDENTICAL SUGAR - PHOSPHATE BACKBONES. ; _pdbx_entry_details.source_details ? _pdbx_entry_details.nonpolymer_details ? _pdbx_entry_details.sequence_details ? _pdbx_entry_details.has_ligand_of_interest ? # loop_ _chem_comp_atom.comp_id _chem_comp_atom.atom_id _chem_comp_atom.type_symbol _chem_comp_atom.pdbx_aromatic_flag _chem_comp_atom.pdbx_stereo_config _chem_comp_atom.pdbx_ordinal C OP3 O N N 1 C P P N N 2 C OP1 O N N 3 C OP2 O N N 4 C "O5'" O N N 5 C "C5'" C N N 6 C "C4'" C N R 7 C "O4'" O N N 8 C "C3'" C N S 9 C "O3'" O N N 10 C "C2'" C N R 11 C "O2'" O N N 12 C "C1'" C N R 13 C N1 N N N 14 C C2 C N N 15 C O2 O N N 16 C N3 N N N 17 C C4 C N N 18 C N4 N N N 19 C C5 C N N 20 C C6 C N N 21 C HOP3 H N N 22 C HOP2 H N N 23 C "H5'" H N N 24 C "H5''" H N N 25 C "H4'" H N N 26 C "H3'" H N N 27 C "HO3'" H N N 28 C "H2'" H N N 29 C "HO2'" H N N 30 C "H1'" H N N 31 C H41 H N N 32 C H42 H N N 33 C H5 H N N 34 C H6 H N N 35 G OP3 O N N 36 G P P N N 37 G OP1 O N N 38 G OP2 O N N 39 G "O5'" O N N 40 G "C5'" C N N 41 G "C4'" C N R 42 G "O4'" O N N 43 G "C3'" C N S 44 G "O3'" O N N 45 G "C2'" C N R 46 G "O2'" O N N 47 G "C1'" C N R 48 G N9 N Y N 49 G C8 C Y N 50 G N7 N Y N 51 G C5 C Y N 52 G C6 C N N 53 G O6 O N N 54 G N1 N N N 55 G C2 C N N 56 G N2 N N N 57 G N3 N N N 58 G C4 C Y N 59 G HOP3 H N N 60 G HOP2 H N N 61 G "H5'" H N N 62 G "H5''" H N N 63 G "H4'" H N N 64 G "H3'" H N N 65 G "HO3'" H N N 66 G "H2'" H N N 67 G "HO2'" H N N 68 G "H1'" H N N 69 G H8 H N N 70 G H1 H N N 71 G H21 H N N 72 G H22 H N N 73 HOH O O N N 74 HOH H1 H N N 75 HOH H2 H N N 76 NH4 N N N N 77 NH4 HN1 H N N 78 NH4 HN2 H N N 79 NH4 HN3 H N N 80 NH4 HN4 H N N 81 # loop_ _chem_comp_bond.comp_id _chem_comp_bond.atom_id_1 _chem_comp_bond.atom_id_2 _chem_comp_bond.value_order _chem_comp_bond.pdbx_aromatic_flag _chem_comp_bond.pdbx_stereo_config _chem_comp_bond.pdbx_ordinal C OP3 P sing N N 1 C OP3 HOP3 sing N N 2 C P OP1 doub N N 3 C P OP2 sing N N 4 C P "O5'" sing N N 5 C OP2 HOP2 sing N N 6 C "O5'" "C5'" sing N N 7 C "C5'" "C4'" sing N N 8 C "C5'" "H5'" sing N N 9 C "C5'" "H5''" sing N N 10 C "C4'" "O4'" sing N N 11 C "C4'" "C3'" sing N N 12 C "C4'" "H4'" sing N N 13 C "O4'" "C1'" sing N N 14 C "C3'" "O3'" sing N N 15 C "C3'" "C2'" sing N N 16 C "C3'" "H3'" sing N N 17 C "O3'" "HO3'" sing N N 18 C "C2'" "O2'" sing N N 19 C "C2'" "C1'" sing N N 20 C "C2'" "H2'" sing N N 21 C "O2'" "HO2'" sing N N 22 C "C1'" N1 sing N N 23 C "C1'" "H1'" sing N N 24 C N1 C2 sing N N 25 C N1 C6 sing N N 26 C C2 O2 doub N N 27 C C2 N3 sing N N 28 C N3 C4 doub N N 29 C C4 N4 sing N N 30 C C4 C5 sing N N 31 C N4 H41 sing N N 32 C N4 H42 sing N N 33 C C5 C6 doub N N 34 C C5 H5 sing N N 35 C C6 H6 sing N N 36 G OP3 P sing N N 37 G OP3 HOP3 sing N N 38 G P OP1 doub N N 39 G P OP2 sing N N 40 G P "O5'" sing N N 41 G OP2 HOP2 sing N N 42 G "O5'" "C5'" sing N N 43 G "C5'" "C4'" sing N N 44 G "C5'" "H5'" sing N N 45 G "C5'" "H5''" sing N N 46 G "C4'" "O4'" sing N N 47 G "C4'" "C3'" sing N N 48 G "C4'" "H4'" sing N N 49 G "O4'" "C1'" sing N N 50 G "C3'" "O3'" sing N N 51 G "C3'" "C2'" sing N N 52 G "C3'" "H3'" sing N N 53 G "O3'" "HO3'" sing N N 54 G "C2'" "O2'" sing N N 55 G "C2'" "C1'" sing N N 56 G "C2'" "H2'" sing N N 57 G "O2'" "HO2'" sing N N 58 G "C1'" N9 sing N N 59 G "C1'" "H1'" sing N N 60 G N9 C8 sing Y N 61 G N9 C4 sing Y N 62 G C8 N7 doub Y N 63 G C8 H8 sing N N 64 G N7 C5 sing Y N 65 G C5 C6 sing N N 66 G C5 C4 doub Y N 67 G C6 O6 doub N N 68 G C6 N1 sing N N 69 G N1 C2 sing N N 70 G N1 H1 sing N N 71 G C2 N2 sing N N 72 G C2 N3 doub N N 73 G N2 H21 sing N N 74 G N2 H22 sing N N 75 G N3 C4 sing N N 76 HOH O H1 sing N N 77 HOH O H2 sing N N 78 NH4 N HN1 sing N N 79 NH4 N HN2 sing N N 80 NH4 N HN3 sing N N 81 NH4 N HN4 sing N N 82 # _ndb_struct_conf_na.entry_id 1QCU _ndb_struct_conf_na.feature 'quadruple helix' # _pdbx_initial_refinement_model.accession_code ? _pdbx_initial_refinement_model.id 1 _pdbx_initial_refinement_model.entity_id_list ? _pdbx_initial_refinement_model.type 'in silico model' _pdbx_initial_refinement_model.source_name Other _pdbx_initial_refinement_model.details 'A-form RNA' # _atom_sites.entry_id 1QCU _atom_sites.fract_transf_matrix[1][1] 0.022828 _atom_sites.fract_transf_matrix[1][2] 0.013180 _atom_sites.fract_transf_matrix[1][3] 0.000000 _atom_sites.fract_transf_matrix[2][1] 0.000000 _atom_sites.fract_transf_matrix[2][2] 0.026359 _atom_sites.fract_transf_matrix[2][3] 0.000000 _atom_sites.fract_transf_matrix[3][1] 0.000000 _atom_sites.fract_transf_matrix[3][2] 0.000000 _atom_sites.fract_transf_matrix[3][3] 0.034282 _atom_sites.fract_transf_vector[1] 0.000000 _atom_sites.fract_transf_vector[2] 0.000000 _atom_sites.fract_transf_vector[3] 0.000000 # loop_ _atom_type.symbol C H N O P # loop_
