Crystal structure of interleukin 8: symbiosis of NMR and crystallography.

The crystal structure of a host defense system chemotactic factor, interleukin 8, has been solved by molecular replacement using as a model the solution structure derived from nuclear magnetic resonance experiments. The structure was refined with 2 A x-ray data to an R factor of 0.187 (0.217 at 1.6 A). A comparison indicates some potential differences between the structure in solution and in the crystalline state. Our analysis also predicts that residues 4 through 9 on the amino terminus and the beta-bend, which includes His-33, may be important for receptor binding.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
