Refinement | Method: SIMULATED ANNEALING, TORSION ANGLE DYNAMICS / Software ordinal: 1 Details: THE SAMPLES USED ARE CONSTRUCTS IN WHICH ONE MOTIF IS TETHERED TO THE C-TERMINUS OF THE FAT DOMAIN VIA A GGSX LINKER AND THE OTHER LD MOTIF IS BOUND AS A FREE PEPTIDE. THE GGS LINKERS ARE ...Details: THE SAMPLES USED ARE CONSTRUCTS IN WHICH ONE MOTIF IS TETHERED TO THE C-TERMINUS OF THE FAT DOMAIN VIA A GGSX LINKER AND THE OTHER LD MOTIF IS BOUND AS A FREE PEPTIDE. THE GGS LINKERS ARE UNSTRUCTURED AND COMPARISON OF SPECTRA LEAD US TO BELIEVE THEY DO NOT IMPOSE ANY CONSTRAINT UPON HOW THE TETHERED LD MOTIFS BIND TO FAT. HOWEVER WHEN ANALYZING THE STRUCTURE IN CYANA, THE PRESENCE OF THE GGS LINKER IN THE SEQUENCE INTERFERS WITH CYANA'S INITIAL ALIGNMENT OF THE 20 LOWEST ENERGY STRUCTURES AND THUS CONFUSES RMSD AND TARGET FUNCTION CALCULATIONS. WE FOUND THAT USING PSEUDO LINKERS IN CYANA RESOLVED THIS PROBLEM WITHOUT CHANGING THE STRUCTURES IN QUESTION AND SO WE CHOSE TO SUBMIT THE STRUCTURES IN THAT WAY. 2RP6 REPRESENTS A COMPOSITE STRUCTURE USING CONSTRAINTS OBTAINED FROM THE 2RP7 AND 2RP9 DATA SETS. IT DOES NOT REPRESENT A NEW CONSTRUCT IN ITSELF, BUT MOST ACCURATELY REPRESENTS THE COMPLETE COMPLEX STRUCTURE BETWEEN PAXILLIN AND FOCAL ADHESION KINASE. | ||||||||||||||||||
