Method SIMULATED ANNEALING STARTING FROM A RANDOM ARRAY OF ATOMS. HIGH TEMPERATURE SIMULATED ANNEALING. RESTRAINED MOLECULAR DYNAMIC AT ROOM TEMPERATURE.
Details THE STRUCTURES ARE BASED ON 1372 TOTAL INTERPROTON DISTANCE RESTRAINTS, 1348 ARE DERIVED FROM NOE DATA AND 44 DERIVED FROM SLOW DEUTERIUM EXCHANGE EXPERIMENTS OF HYDROGEN BONDED AMIDE PROTONS IN REGULAR SECONDARY STRUCTURE MOTIFS. THE RESTRAINT SET INCLUDES 102 DIHEDRAL RESTRAINTS, 66 PHI, 34 KHI1, 2 KHI2. FINAL STRUCTURES ARE REFINED AGAINST THE FULL DESCRIPTION OF AMBER4 FORCE FIELD WITH REDUCED CHARGES FOR FORMALLY CHARGED GROUPS AS ARG, LYS, ASP, GLU RESIDUES.
NMR Ensemble Information
Conformer Selection Criteria STRUCTURES WITH ACCEPTABLE COVALENT GEOMETRY. STRUCTURES WITH FAVORABLE NON- BOND ENERGY. STRUCTURES WITH THE LEAST RESTRAINT VIOLATIONS. STRUCTURES WITH THE LOWEST ENERGY.
