Refined structure of yeast apo-enolase at 2.25 A resolution.
B.Stec, L.Lebioda.
The crystal structure of apo-enolase from baker's yeast (Saccharomyces cerevisiae) was established at 2.25 A resolution using a restrained least-squares refinement method. Based on 21,077 independent reflections of better than 8 A resolution, a final R-factor of 15.4% was obtained with a model obeying standard geometry within 0.017 A in bond length and 3.5 degrees in bond angles. The upper limit for the co-ordinate accuracy of the atoms was estimated to be 0.18 A. The refinement confirmed the heterodox, non-parallel character of the 8-fold beta alpha-barrel domain with beta beta alpha alpha(beta alpha)6 topology. The reported structure for which the data were collected at pH 5.0 represents an apo-form of the enzyme. Of the three carboxylic ligands that form the conformational metal ion binding site two, Glu295 and Asp320, are very close and presumably form a strong acidic type hydrogen bond with the proton partially replacing the electric charge of the physiological cofactor Mg2+. The single sulfate ion found in the structure is in the active site cavity, co-ordinated to the side-chains of Lys345 and Arg374, and to the N atom of Ser375. It is located about 7.4 A from the conformational metal ion binding site. It occupies the site in which the phosphate group of the substrate binds.

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 code is shown on the right.
