REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : STRUCTURAL FITTING 2.0 REMARK 3 AUTHORS : NEVZOROV, A.A AND OPELLA, S.J. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THIS STRUCTURE WAS CALCULATED BY REMARK 3 USING A STRUCTURAL FITTING ALGORITHM THAT FINDS TORSION ANGLES REMARK 3 BETWEEN CONSECUTIVE RESIDUES BASED ON THEIR 15N CHEMICAL REMARK 3 SHIFT, 1H-15N DIPOLAR COUPLING FREQUENCIES AND RAMACHANDRAN REMARK 3 MAPS. ONE HYDROPHOBIC MATCHING AND ONE LOOSE HELIX-HELIX REMARK 3 DISTANCE RESTRAINTS WERE USED
