wwPDB validation report of PDB entry 3BRQ

The Friedel pairs were used in phasing. HYDROGENS HAVE BEEN ADDED IN THE RIDING POSITIONS

Crystal structure of the Escherichia coli transcriptional repressor ascG

AUTHORS STATE THAT THEY DO NOT HAVE AN EVIDENCE THAT THIS PROTEIN IS A DIMER, BUT IT IS KNOWN THAT MANY OF THESE TRANSCRIPTIONAL REPRESSORS DO DIMERIZE. THEREFORE, THE DIMERIC ASSEMBLY THAT IS PREDICTED BY PISA AND SHOWN IN REMARK 350 IS MOST LIKELY THE ASSEMBLY OF THE BIOLOGICAL UNIT.

The largest off-origin peak in the Patterson function is 4.70% of the height of the origin peak. No significant pseudotranslation is detected.
