WITH PROLSQ, NO RFREE WAS CALCULATED. ********* STEREOCHEMISTRY REMARKS: BECAUSE discretely disordered (MULTIPLE SUBSTATE) PROTEIN RESIDUES EACH HAVE OCCUPANCY LESS THAN ONE, THEY ARE DIFFICULT TO ACCURATELY REFINE. THE GEOMETRY CAN BE DISTORTED (IS POORLY DETERMINED). IN THE CASE OF THR39, THE BACKBONE IS CLEARLY DISORDERED, WITH VERY SMALL DEVIATIONS BETWEEN SUBSTATES (~0.1 A), AND THAT WAS NOT INCLUDED IN THE MODEL. HENCE THEre may be LARGE ERRORS INVOLVING CA.
