Single chain trimer HLA-A*02:01 (Y108C) with HPV.16 E7 peptide YMLDLQPETTDL

The analyses of the Patterson function reveals a significant off-origin peak that is 38.65 % of the origin peak, indicating pseudo-translational symmetry. The chance of finding a peak of this or larger height by random in a structure without pseudo-translational symmetry is equal to 3.5716e-04. The detected translational NCS is most likely also responsible for the elevated intensity ratio. See the relevant section of the logfile for more details.
