    Refinement
    Method simulated annealing and restrained energy minimization in vacuum
    Details The structures were calculated using the constraints: 2382 meaningful upper distance limits, 42 dihedral phi angles, 41 dihedral psi angles and 42 proton pairs stereospecifically assigned. The disulphide bridge between C57 and C146 was introduced with the upper and lower distances limits between the CB and SG atoms of the two side chains.
