Details REFINEMENT DETAILS CAN BE FOUND IN THE PRIMARY CITATION. THE INITIAL STRUCTURE OF THE EI DIMER COMPLEXED WITH HPR WAS CONSTRUCTED AS A HYBRID OF THE CRYSTAL STRUCTURE OF PHOSPHORYLATED EI INTERMEDIATE CAPTURED BY THE INHIBITOR OXALATE (PDB CODE 2HWG) AND THE NMR STRUCTURE OF THE EIN-HPR COMPLEX (PDB CODE 3EZA). THROUGHOUT THE STRUCTURE DETERMINATION, THE BACKBONE ATOMIC COORDINATES OF EACH EIN-HPR COMPLEX (RESIDUES 1-254 AND 601-685) WERE TREATED AS RIGID BODIES, WITH THE TWO SYMMETRY RELATED EIC DOMAINS (RESIDUES 262- 573) HELD FIXED IN SPACE. COORDINATES IN THE LINKER REGION (RESIDUES 255-261) WERE ALLOWED VARYING DEGREES OF FREEDOM DURING THE CALCULATION THROUGH THE USE OF THE INTERNAL VARIABLE MODULE (IVM) OF XPLOR-NIH. THE ENSEMBLE OF CALCULATED STRUCTURES FELL IN TWO CLUSTERS, THE REGULARIZED REFINED MEAN OF EACH IS INCLUDED BELOW AS MODELS 1 AND 2, RESPECTIVELY.
