wwPDB validation report of PDB entry 3P4M

H-2 class I histocompatibility antigen, K-B alpha chain

H-2 class I histocompatibility antigen, K-B alpha chain, Beta-2-microglobulin, NP205-LCMV epitope, YTVKYPNL
Crystal Structure of H2-Kb in complex with the NP205-LCMV epitope YTVKYPNL, an 8-mer peptide from the LCMV

The analyses of the Patterson function reveals a significant off-origin peak that is 37.78 % 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 4.0718e-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.
