Simulated annealing, restrained molecular dynamics | The first six residues of the protein could not be assigned due to the disorder of the N-terminus region. These are shown as missing residues in remark 465 in all the models. The anomalous torsion angles observed for his 107 and glu 105 are also found in the related pdbs 1dzd and 1dzc of fgf-1. Most of the peptide bonds that deviate significantly from both cis and trans conformation, shown in remark 500, correspond to residues implicated in the binding of the ligand. | XwinNMR |
