DUE TO POORLY DEFINED DENSITY, THE FOLLOWING ATOMS: (CE,NZ) AND (CG,CD,CE,NZ) ARE MISSING FROM RESIDUES B31 E B37, RESPECTIVELY. FOR RESIDUE A37 ONLY A SINGLE SIDE CHAIN CONFORMATION HAS BEEN MODELED WHICH IS ALTERNATIVE TO A34 SIDE CHAIN AT MINOR OCCUPANCY. THE NUMBER OF PROTEIN ATOMS USED IN REFINEMENT (GIVEN ABOVE) INCLUDES CONTRIBUTIONS FROM THE MULTIPLE CONFORMERS AND ATOMS BELONGING TO THE IAS RESIDUES.
