X-ray structure of monoclinic turkey egg lysozyme at 1.3 A resolution.
Monoclinic crystals of turkey egg lysozyme (TEL, E.C. were obtained from 2.2 M ammonium sulfate solution at pH 4.2. They belong to space group P2(1) with unit-cell dimensions a = 38.07, b = 33.20, c = 46.12 A and beta = 110.1 degrees, and contain one molecule in the asymmetric unit (V(m) = 1.91 A(3) Da(-1)). The three-dimensional structure of TEL was solved by the method of multiple isomorphous replacement with anomalous scattering. Area detector data to 1.5 A resolution from native and heavy-atom derivatives were used for the structure determination. The structure was refined by the simulated-annealing method with diffraction data of 10-1.30 A resolution. The conventional R factor was 0.189. The root-mean-square deviations from ideal bond distances and angles were 0.016 A and 2.9 degrees, respectively. The backbone structure of TEL is very similar to that of hen egg lysozyme (HEL) and the difference in seven amino-acid residues does not affect the basic folding of the polypeptide chain. Except for the region from Gly101 to Gly104, the geometry of the active-site cleft is conserved between TEL and HEL. The Gly101 residue is located at the end of the sugar-binding site and the structural change in this region between TEL and HEL is considered to be responsible for the difference in their enzymatic properties.

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.
