| SEMIRIGID AND FLEXIBLE SIMULATED ANNEALING | REFINEMENT DETAILS CAN BE FOUND IN THE JRNL CITATION ABOVE REFERENCE HADDOCK AUTH C. DOMIGUEZ, R. BOELENS, A.M.J.J. BONVIN TITLE HADDOCK A PROTEIN-PROTEIN DOCKING APPROACH BASED ON BIOCHEMICAL OR BIOPHYSICAL INFORMATION REF J.AM. CHEM.SOC,V125,P1731,2003 COORDINATES FOR E. COLI SECA (RESIDUES 9-228, 349-836)WERE OBTAINED FROM PDB ENTRY 2FSF. THE PREPROTEIN BINDING DOMAIN (RESIDUES 229-348) WAS MODELLED BASED ON THE AVAILABLE STRUCTURE OF T. THERMOPHILUS, CSI DATA AND NOES ON THE ISOLATED DOMAIN. TWO SINGLE CYSTEINE VARIANTS (POSITIONS 7 AND 25) WERE PREPARED AND CROSSLINKED WITH MTSL. PARAMAGNETIC RELAXATION ENHANCEMENT (PRE) VALUES FOR METHYL PROTONS OF VAL, LEU, ILE AND MET RESIDUES WERE QUANTIFIED FROM TWO 13C-HMQC SPECTRA (PARAMAGNETIC AND DIAMAGNETIC). PRES WERE CONVERTED TO DISTANCE RESTRAINTS, WHICH WERE USED FOR SUBSEQUENT STRUCTURE CALCULATION OF THE SECA-SIGNAL PEPTIDE COMPLEX. | HADDOCK-CNS |
