'''Correction of X-ray Intensities from an HslV-HslU co-crystal containing lattice translocation defects'''<br />


==Overview==
==Correction of X-ray Intensities from an HslV-HslU co-crystal containing lattice translocation defects==
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.

== Function ==
[https://www.uniprot.org/uniprot/HSLU_ECOLI HSLU_ECOLI] ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.<ref>PMID:8662828</ref> <ref>PMID:8650174</ref> <ref>PMID:9288941</ref> <ref>PMID:9393683</ref> <ref>PMID:10452560</ref> <ref>PMID:10419524</ref> <ref>PMID:15696175</ref>
