REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : CNS 1.1 REMARK 3 AUTHORS : BRUNGER, A. T., ADAMS, P. D., CLORE, G. M., REMARK 3 DELANO, W. L., GROS, P., GROSSE-KUNSTLEVE, R. REMARK 3 W., JIANG, J. S., KUSZEWSKI, J., NILGES, M., REMARK 3 PANNU, N. S. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: MODELS WERE REFINED IN CNS 1.1 REMARK 3 PROGRAM. CONSENSUS SECONDARY STRUCTURE ELEMENTS AND FRET PROBE REMARK 3 OLIGOMERS WERE ASSEMBLED AND MOVED INTO RANDOM CONFORMATIONS REMARK 3 PRODUCED AS STARTING MODELS. SECONDARY STRUCTURE AND A-FORM REMARK 3 HELIX WERE RESTRAINED USING DISTANCES AND ANGLES FROM STANDARD REMARK 3 A-FORM RNA HELICES (NUCLEIC ACID DATABASE). ADDITIONAL REMARK 3 RESTRAINTS WERE EXPERIMENTAL DISTANCES FROM FRET MEASUREMENTS REMARK 3 BETWEEN RNA OLIGOMER PROBES. STRUCTURE SHOWN WAS LOWEST ENERGY REMARK 3 AFTER SIMULATED ANNEALING REFINEMENT. FRET DISTANCE RESTRAINTS REMARK 3 WERE: PNA2NTMR TO PNA3NFL, 57 ANGSTROMS; PNA2NTMR TO PNA3CFL, REMARK 3 52 ANGSTROMS; PNA2NTMR TO PNA1CFL, 52 ANGSTROMS; PNA2NTMR TO REMARK 3 PNA1NFL, 50 ANGSTROMS; PNA2CTMR TO PNA3NFL, 62 ANGSTROMS; REMARK 3 PNA1NTMR TO PNA3NFL, 51 ANGSTROMS; PNA1NTMR TO PNA3CFL 56 REMARK 3 ANGSTROMS; PNA1CTMR TO PNA3NFL 61 ANGSTROMS; WHERE N INCATES REMARK 3 THE AMINO TERMINUS OF PNA PROBE (MODELED AS A 5' RNA END) AND REMARK 3 C INDICATES THE CARBOXY TERMINUS OF A PNA PROBE (MODELED AS A REMARK 3 3' RNA END), TMR IS THE TETRAMETHYLRHODAMINE FRET PROBE AND FL REMARK 3 IS THE FLUORESCEIN FRET PROBE.
