NSP15 is a uridine-specific endoribonuclease that functions as a hexamer. The SAXS sample was prepared in the presence of Mn²⁺ ions, which are essential for its enzymatic activity and RNA binding. \r\nThe complex was modeled as a single scattering particle composed of six NSP15 monomers, each associated with a 9-mer RNA, and validated through molecular weight estimation from both I(0) and Porod analysis. The SAXS profile supports a monodisperse and compact hexameric assembly of NSP15 in solution. The data correlate well with the known crystallographic structure (e.g., PDB: 7N33), indicating the preservation of the oligomeric state and RNA interactions in solution under physiological ionic and metal conditions.","experiment_description":null,"tags":[],"intensity_unit":"arbitrary","experimental_mw":244.1,"experimental_mw_error":null,"guinier_i0_mw":208.0,"guinier_i0_mw_error":null,"porod_mw":222.0,"porod_mw_error":null,"pddf_i0":51800.0,"pddf_i0_error":null,"guinier_i0":52508.4,"guinier_i0_error":842.17,"pddf_rg":4.66,"pddf_rg_error":0.417,"guinier_rg":4.72,"guinier_rg_error":0.18,"pddf_dmax":13.83,"pddf_dmax_error":null,"porod_volume":356.0,"porod_volume_error":null,"estimated_volume":null,"estimated_volume_error":null,"guinier_point_first":9,"guinier_point_last":30,"pddf_point_first":null,"pddf_point_last":null,"i0_calibration_standard_data":null,"intensities_log_log_plot":"SASDX67_datloglog_img.png","symmetry":null,"last_modified":"2025-09-17T14:35:36.817367+02:00","bragg_peak":[]}
