REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR_NIH 2.16.0 REMARK 3 AUTHORS : C.D. SCHWIETERS, J.J. KUSZEWSKI, N. TJANDRA AND REMARK 3 G.M. CLORE REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: STRUCTURES OF THE HIV-1 TAR RNA/L-22 REMARK 3 COMPLEX WERE CALCULATED WITH XPLOR-NIH. BACKBONE DIHEDRAL REMARK 3 ANGLE RESTRAINTS FOR THE PEPTIDE WERE ESTIMATED USING CHEMICAL REMARK 3 SHIFT DATA AND TALOS. STRUCTURES WERE ORIGINALLY CALCULATED REMARK 3 WITHOUT RDCS TO TEST FOR CONVERGENCE AND ADHERENCE TO THE NOE REMARK 3 DATA. RDC RESTRAINTS WERE THEN APPLIED AS SUSCEPTIBILITY REMARK 3 ANISOTROPY RESTRAINTS WITH A HARMONIC POTENTIAL WELL.
