In protein structure prediction, a considerable number of alternative models are usually produced from which subsequently the final model has to be selected. Thus, a scoring function for the identification of the best model within an ensemble of alternative models is a key component of most protein structure prediction pipelines. QMEAN, which stands for(More)
Beta-D-xylosidases are hemilcellulases that hydrolyze short xylooligosaccharides into xylose units. Here, we describe the characterization and kinetic analysis of a family 43 beta-xylosidase from Geobacillus stearothermophilus T-6 (XynB3). Enzymes in this family use an inverting single-displacement mechanism with two conserved carboxylic acids, a general(More)
A simple, new, systematic method has been developed to evaluate the structural similarity of proteins. Firstly, similar protein fragments of a definable length are detected, combined in pairs and superimposed. The fits are improved until a maximum number of C alpha atoms show a distance below a given threshold value. The final number of matching C alpha(More)

A geometric docking algorithm based upon correlation analysis for quantification of geometric complementarity between protein molecular surfaces in close interfacial contact has been developed by a detailed optimization of the conformational search of the algorithm. In order to reduce the entire conformation space search required by the method a(More)
