Details | BIOMOLECULE: THIS ENTRY CONTAINS ONE COLLAGEN TYPE I MOLECULE. FOR RELATION TO THE FIBRILLAR PACKING OF COLLAGEN MOLECULES/MICRO-FIBRIL, REFER TO CITATION. IN SUMMARY: EACH COLLAGEN MOLECULE IS STAGGERED BY AN INTEGER MULTIPLE OF THE C-CELL AXIS. THE STRUCTURE CAN BE EXTENDED IN THE AXIAL (~C-CELL AXIS) DIRECTION BY APPLYING THE FOLLOWING TRANSLATION: NX,0Y,NZ TO THE MOLECULE, WHERE N IS AN INTEGER. A VISUALIZATION OF FIVE SUCCESSIVE 'D'-REPEATS OF THE BIOMOLECULE / MICRO-FIBRIL CAN BE OBTAINED FROM THESE COORDINATES BY APPLYING THE FOLLOWING TRANSLATIONS TO NINE COORDINATE SETS: A) 0, 0, 0; B) -1, 0,-1; C) -2, 0,-2; D) -3, 0,-3; E) -4, 0,-4; B1) 1, 0, 1; C1) 2, 0, 2; D1) 3, 0, 3; E1) 4, 0, 4. |

INITIAL REFINEMENT OF WHOLE MOLECULAR PATHS WAS PERFORMED IN THE STEPWISE FASHION DESCRIBED IN THE CITED PUBLICATION. MODEL STRUCTURE FACTORS WHERE INITIALLY GENERATED FROM THE WHOLE RESIDUE SCATTERING FACTORS OF HULMES ET AL 1977 WHICH WERE SUBSTITUTED FOR THE CALPHA POSITIONS AND THE SQUARE FC'S WERE CALCULATED FOR COMPARISON BETWEEN A SIMULATED DIFFRACTION PATTERN AND THE OBSERVED PATTERNS. STRUCTURE FACTORS FROM THE FINAL MODEL WERE GENERATED IN THE NORMAL MANNER FOR REFINEMENT OF THE TELOPEPTIDE CONFORMATIONS USING CNS (SEE ABOVE). TWO ROUNDS OF Q-FACTOR REFINEMENT FOLLOWED BY ONE ROUND OF CONSTRAINED THEN UNCONSTRAINED ANNEALING FOR THE WHOLE STRUCTURE. THE R- FACTOR WHEN MEASURED VIA SIMULATED/OBSERVED DIFFRACTION PATTERN COMPARISON WAS FOUND TO BE 16.7% AND 6.6% BY MEASURE OF THE INTERGRATED STRUCTURE FACTORS. REFLECTIONS MISSING FROM THE MERIDONAL(OOL) SERIES WERE EITHER TOO WEAK TO MEASURE AND/OR VAIRED SIGNIFICANTLY BETWEEN COLLECTED PATTERNS (SEVEN IN TOTAL). THE FIRST FIVE REFLECTIONS WHERE EXCLUDED DUE TO THEIR LOW RESOLUTION (677.9 TO ~120 ANGSTROMS). EXLUDED REFLECTIONS ARE NOT INCLUDED IN THE 414 TOTAL. THE COORDINATES CONTAIN CA ATOMS ONLY.
