REMARK 3 PROGRAM : DIANA REMARK 3 AUTHORS : WUTHRICH REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THREE DIMENSIONAL SOLUTION STRUCTURE REMARK 3 OF RECOMBINANT SYRIAN HAMSTER PRION PROTEIN RPRP(90-231) WAS REMARK 3 DETERMINED BY NMR RESTRAINTS USING THE PROGRAM DIANA, FOLLOWED REMARK 3 BY ENERGY MINIMIZATION WITH AMBER 4.1. TOTAL NUMBER OF REMARK 3 EXPERIMENTAL DISTANCE RESTRAINTS IS 2401 (858 INTRARESIDUE, REMARK 3 753 SEQUENTIAL (I,I+1), 195 (I,I+2), 233 (I,I+3), 109 (I,I+4) REMARK 3 AND 253 LONG RANGE). SECONDARY STRUCTURE HYDROGEN BOND REMARK 3 RESTRAINTS (44) WERE INCLUDED IN THE REFINEMENT. NOE REMARK 3 CONNECTIVITIES AND SECONDARY STRUCTURE BASED ON CHEMICAL REMARK 3 SHIFTS WERE USED TO IDENTIFY THOSE H-BONDS. IN AVERAGE, 30 OUT REMARK 3 OF THE 2401 RESTRAINTS WERE VIOLATED BY MORE THAN 0.5 REMARK 3 ANGSTROMS IN THE 15 DEPOSITED STRUCTURES. RMSD OF BACKBONE REMARK 3 HEAVY ATOMS OF RESIDUES 128 - 227 IS LESS THAN 1.9 FOR THE 15 REMARK 3 STRUCTURES. NOTE: THE PROCHIRAL GROUPS WERE NOT REMARK 3 STEREOSPECIFICALLY ASSIGNED, AND AROMATIC RING PROTONS ARE REMARK 3 ONLY PARTIALLY ASSIGNED. THE REFINEMENT OF HIGH RESOLUTION REMARK 3 STRUCTURE IS IN PROGRESS. REFINEMENT DETAILS CAN ALSO BE FOUND REMARK 3 IN THE JRNL CITATION ABOVE.
