REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : NULL REMARK 3 AUTHORS : NULL REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURE IS FORMED OF FOUR REMARK 3 EQUIVALENT TCC STRANDS DESIGNATED A, B, C, D. STRANDS A AND C, REMARK 3 CONNECTED BY TWO HEMI-PROTONATED BASE PAIRS (C2.C2+ AND C3.C3+ REMARK 3 ), FORM A PARALLEL-STRANDED DUPLEX. THE RELATION BETWEEN REMARK 3 STRANDS B AND D IS THE SAME AS THAT BETWEEN STRANDS A AND C. REMARK 3 THE STRANDS OF EACH DUPLEX ARE RELATED BY A LONGITUDINAL TWO- REMARK 3 FOLD SYMMETRY AXIS. THE DUPLEXES HAVE THE SAME LONGITUDINAL REMARK 3 AXIS, AND THEY ARE ANTI-PARALLEL. THEIR HEMI-PROTONATED C.C+ REMARK 3 BASE PAIRS ARE INTERCALATED FACE-TO-FACE. THE DUPLEXES CAN BE REMARK 3 TRANSFORMED INTO ONE ANOTHER BY A 180 DEGREE ROTATION AROUND A REMARK 3 TWO-FOLD AXIS PERPENDICULAR TO THE LONGITUDINAL AXIS, AND REMARK 3 CONSEQUENTLY AROUND A THIRD AXIS PERPENDICULAR TO THE FIRST REMARK 3 TWO. THE H3 IMINO PROTONS OF THE HEMI-PROTONATED C.C+ PAIRS REMARK 3 WERE NOT INCORPORATED IN THE COMPUTATIONS.
