THE NF-YA MODEL COMPRISES RESIDUES 232-293. POOR DENSITY IS PRESENT FOR THE 232-235 SEGMENT, WHILE NO INTERPRETABLE ELECTRON DENSITY WAS PRESENT FOR THE 294-307 SEGMENT. NF-YB AND NF-YC COMPRISE RESIDUES 50-141 AND 40-119, RESPECTIVELY. FOR THE FIRST TWO NF-YB N-TERMINAL RESIDUES, THE FIRST THIRTEEN NF-YC N-TERMINAL RESIDUES AND THE LAST NF-YC C- TERMINAL RESIDUES NO ELECTRON DENSITY WAS AVAILABLE. FINAL STRUCTURE HAS NO RESIDUES IN THE DISALLOWED REGION OF THE RAMACHANDRAN PLOT AS DEFINED IN THE CCP4 PROCHECK PROGRAM.
