Sidechain assignments were completed manually. The oligomeric state was confirmed to be a dimer from sedimentation-equilibrium analysis (Kd =0.3uM) and static light scattering experiment that reported 90% of the protein in a dimer with a molecular weight of 15.03kD. |

Constraints for the dimer interface were obtained from the x-filtered NOESY data and slow exchanging amides from H/D exchange. 100 structures were calculated and 20 best conformers were then refined in a shell of water using CNS. Initial dihedral angle constraints were obtained from TALOS. Final structure quality factors determined using PSVS software: ordered residues are defined as (10-53,212-236,238-251). (a)RMSD(ordered residues) all Backbone atoms: 0.7A; all heavy atoms: 1.0A. (b) Ramchandran statistics for all ordered residues: Most favoured region: 93.1%; Additionally allowed region: 6.6%; Generously allowed region 0.1% and disallowed region: 0.2%. (c) Procheck scores for all ordered residues (Raw/Z) phi-psi -0.11/-0.12; All: -0.07/-0.41; (d) MolProbity clash score (Raw/Z): 16.97/-1.39. (e) RPF scores for the goodness of fit to NOESY data: Recall :0.913; Precision:0.849; F-measure:0.88; Final DP score :0.703 | ||||||||||||||||||||
