Correction of X-ray Intensities from an HslV-HslU co-crystal containing lattice translocation defects
Overview
Because of lattice-translocation defects, two identical but translated, lattices can coexist as a single coherent mosaic block in a crystal. The, observed structure in such cases is a weighted sum of two identical but, translated structures, one from each lattice; the observed structure, factors are a weighted vector sum of the structure factors with identical, unit amplitudes but shifted phases. The correction of X-ray intensities, from a single crystal containing these defects of the hybrid HslV-HslU, complex, which consists of Escherichia coli HslU and Bacillus subtilis, HslV (also known as CodW), is reported. When intensities are not, corrected, a biologically irrelevant complex (with CodW from one lattice, and HslU from another) is implied to exist. Only upon correction does a, biologically functional CodW-HslU complex structure emerge.
About this Structure
1YYF is a Protein complex structure of sequences from Bacillus subtilis and Escherichia coli with ADP as ligand. The following page contains interesting information on the relation of 1YYF with [AAA+ Proteases]. Full crystallographic information is available from OCA.
