ORIGINAL MODEL WAS PUBLISHED WITHOUT ANY REMARK 3 REFINEMENT. A MODEL WAS PLACED TO FIT TO THE EXPERIMENTALLY REMARK 3 OBTAINED MAP AND WAS CHECKED WITH RAMACHANDRAN PLOT BY USING REMARK 3 PROGRAM:PROCHECK. IT SHOWED A CONFIGURATION WITH RESIDUES 80.9% IN REMARK 3 MOST FAVORABLE REGIONS, 15.5% IN ADDITIONAL ALLOWED REGIONS, 3.6% REMARK 3 IN GENEROUSLY ALLOWED REGIONS AND 0% IN DISALLOWED REGIONS. REMARK 3 REMARK 3 SPECIAL POSITION/STRUCTURE DETERMINATION REMARK 3 THE STRUCTURE WAS DETERMINED FROM TWO DIMENSIONAL CRYSTALS REMARK 3 AND THEREFORE THE POSITION IN THE DIRECTION ALONG C AXIS REMARK 3 IS ARBITRARY. IN ORDER TO HAVE POSITION OF THE CURRENT REMARK 3 MODEL COMPARABLE TO 1BRD AND 2BRD IN PDB, THE AUTHORS REMARK 3 FITTED THE MODEL TO 2BRD BY USING LSQ_EXP AND LSQ_MOL REMARK 3 FUNCTIONS IN 4D_ONO PROGRAM AUTHORED BY ALWYN JONES. THE REMARK 3 MATCHED POSITIONS ARE CA IN THE FOLLOWING ZONES: 10-25, REMARK 3 43-60, 82-98, 113-126, 135-145, 175-190, 204-222.
