wwPDB validation report of PDB entry 4MO1

truncation: 1-37; C-terminus tag: LEHHHHHH

CYS108 SIDE CHAIN IS COVALENTLY MODIFIED BASED ON THE ELECTRON DENSITY. HOWEVER, THE IDENTITY OF THE MODIFYING GROUP IS NOT KNOWN.THE EXTRA ELECTRON DENSITY IS CURRENTLY MODELED BY WATERS 605, 640, 668 AND 669.

Crystal structure of antitermination protein Q from bacteriophage lambda. Northeast Structural Genomics Consortium target OR18A.

The analyses of the Patterson function reveals a significant off-origin peak that is 21.80 % 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 6.5055e-03. The detected translational NCS is most likely also responsible for the elevated intensity ratio. See the relevant section of the logfile for more details.
