wwPDB validation report of PDB entry 1KPK

This structure is homologous to the crystal structure of the ClC chloride channel from S. typhimurium (1KPL).

Strict 6-fold NCS constraints were maintained during refinement. BULK SOLVENT MODEL USED.

Crystal Structure of the ClC Chloride Channel from E. coli

The biologically active assembly is a homodimer. The three biological dimers in the asymmetric unit are composed of protein chains A and B, C and D, and E and F.

The largest off-origin peak in the Patterson function is 15.85% of the height of the origin peak. No significant pseudotranslation is detected.
