REMARK 3 PROGRAM : SIMPSON, MODELLER 6.1 REMARK 3 AUTHORS : BAK, RASMUSSEN, NIELSEN (SIMPSON), SALI, BLUNDELL REMARK 3 (MODELLER) REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: TWO-SPIN REDOR CURVES WERE SIMULATED REMARK 3 USING A FORTRAN PROGRAM. THREE-SPIN REDOR CURVES FOR THE C -F REMARK 3 EXPERIMENT WERE SIMULATED USING THE SIMPSON PROGRAM. THE INPUT REMARK 3 DISTANCES AND ANGLES IN THE THREE-SPIN SIMULATION WERE OBTAINED REMARK 3 FROM MODEL BUILDING. THE SIMULATIONS ASSUMED DELTA-FUNCTION REMARK 3 PULSES FOR ALL PI PULSES. MODELS THAT WERE POTENTIALLY REMARK 3 CONSISTENT WITH ALL THE EXPERIMENTALLY MEASURED DISTANCES WERE REMARK 3 CREATED USING MODELLER. IN ADDITION TO THE REDOR-BASED REMARK 3 RESTRAINTS, THE INPUT FILE INCLUDED A RESTRAINT TO PRESERVE THE REMARK 3 INTRAMOLECULAR HYDROGEN BOND LADDER OF EACH MONOMER, AND A REMARK 3 RESTRAINT TO MAINTAIN MONOMER SYMMETRY.

THE 15N{ REMARK 210 13C} AND 13C{1H} REDOR EXPERIMENTS WERE CARRIED OUT ON A 1H/13C/ REMARK 210 15N TRIPLE RESONANCE MAS PROBE. SPINNING SPEEDS WERE REGULATED REMARK 210 TO 3 HZ USING A PNEUMATIC CONTROL UNIT. 13C AND 15N CHEMICAL REMARK 210 SHIFTS WERE REFERENCED EXTERNALLY TO THE 13C SIGNAL OF ALPHA-GLY REMARK 210 AT 176.4 PPM ON THE TMS SCALE AND THE 15N SIGNAL OF N-ACETYL- REMARK 210 VALINE AT 122 PPM, RESPECTIVELY. THE 13C{19F} REDOR EXPERIMENTS, REMARK 210 WHERE THE NUCLEUS IN THE BRACKET IS THE UNOBSERVED DEPHASING REMARK 210 SPIN, WAS CONDUCTED ON A 4-MM MAGIC-ANGLE SPINNING (MAS) PROBE REMARK 210 EQUIPPED WITH A BRUKER HFX UNIT, WHICH ALLOWS SIMULTANEOUS REMARK 210 TUNING OF 1H AND 19F ON THE 1H CHANNEL.
