NMR Refinement
Method	Details	Software
simulated annealing combined with molecular dynamics in torsion angle space	The model of L7 dimer with the one unordered, extended hinge region and the second hinge region in helical conformation was calculated using the mean NMR structures of its N- and C-terminal domains and NMR derived constraints obtained for U-15N protein L7, as well as angle constraints for the helical hinge region, which are obtained from X-Ray structure of protein L12 from T.maritima (PDB code 1DD3).
