wwPDB validation report of PDB entry 3IQ5

Flat collimating mirror, double crystal monochromator, toroid focusing mirror

Crystal structure of E. coli cytochrome b562 with engineered c-type heme linkages

Crystal Structure of a 16-Helix Bundle Architecture Produced by the Zinc-Mediated Self Assembly of Four Cytochrome cb562 Molecules

Crystal structure of a tetrameric Zn-bound cytochrome cb562 complex with covalently and non-covalently stabilized interfaces

Crystal structure of an engineered metal-free tetrameric cytochrome cb562 complex templated by Zn-coordination

THE ASYMMETRIC UNIT CONTAINS TWO DIMERIC HALVES (CHAINS A/C, AND CHAINS B/D) OF TWO TETRAMERS. THE GENERATING OF FULL TETRAMERS IS DESCRIBED IN REMARK 350

The analyses of the Patterson function reveals a significant off-origin peak that is 38.11 % 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 3.8733e-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.
