simulated annealing, Water refinementStructure calculations were carried out with the standard simulated annealing protocol by using the CNS 1.1 program. Several rounds of calculations were used to eliminate the ambiguity in the assignment.Final structures were refined by the explicit water model using the OPLS force field in RECOORD and evaluated with PROCHECK-nmr.CNS
