REMARK 5 REMARK 5 EXPERIMENTAL DETAILS REMARK 5 DESIGNED USING SCULPT (INTERACTIVE SIMULATIONS, INC.), AN REMARK 5 INTERACTIVE MODELING PROGRAM WITH REAL-TIME ENERGY REMARK 5 MINIMIZATION (REF. 1). IT CONSTRAINS BOND LENGTHS, REMARK 5 ANGLES, AND SINGLE-VALUE TORSION ANGLES TO IDEAL VALUES REMARK 5 AND APPLIES RESTRAINT FORCES TO NON-BONDED INTERACTIONS, REMARK 5 MULTIPLE-VALUE TORSION ANGLES, AND USER TUGS. THE DESIGN REMARK 5 STARTED FROM A 2-SS CORE FOUND IN MANY UNRELATED SMALL REMARK 5 PROTEINS (REF. 2), ONTO WHICH NEW LOOPS WERE MODELED. IT REMARK 5 IS BEING PRODUCED BY PEPTIDE SYNTHESIS BY DAVID KING, UC REMARK 5 BERKELEY, AND WILL BE DESCRIBED IN PRINT ONCE IT HAS BEEN REMARK 5 CHARACTERIZED.
