MONOMER STRUCTURE: DETERMINED WITH SIMULATED ANNEALING PROTOCOL THAT REFINES ALL INTRAMONOMER NOES, SIDECHAIN J-COUPLINGS, AND BACKBONE RDCS. 2. PENTAMER STRUCTURE: DETERMINED BY OUR COMPLETE SCS APPROACH. TRADITIONAL NMR PROTOCOLS FOR SYMMETRIC HOMO-OLIGOMERS (USED FOR STRUCTURES OF PDB ID 1ZLL) ARE BASED ON SIMULATED ANNEALING TECHNIQUES AND COULD GET TRAPPED IN LOCAL MINIMA. OUR COMPLETE SCS SEARCH APPROACH AVOIDS BIAS AND RETURNS ALL CONSISTENT, WELL-PACKED STRUCTURES TO WITHIN A USER-DEFINED SIMILARITY LEVEL. ENERGY-MINIMIZATION IS USED ONLY AT A LATER STAGE AFTER THE ENSEMBLE OF STRUCTURES THAT SATISFY THE DATA HAVE BEEN IDENTIFIED, HENCE ENSURING THAT NO CONSISTENT WELL-PACKED CONFORMATION IS MISSED. | ||||||||||||
