Prediction of Protein-Ligand and Protein-Protein Interactions based on Local Surface Similarity
No full textThe three-dimensional structure of a protein determines its function. This thesis describes a suite of methods for the problem of protein binding site recognition, based on a spin-images representation of the molecular surface. A procedure for cavity detection is coupled with a procedure for the recog- nition of similar regions in two proteins, and applied to the comparison of two protein's cavities, the all-to-all pairwise comparison of a set of cavities, and the recognition of multiple binding sites in one cavity. All the presented methods can be used to screen large collections of proteins.La struttura tridimensionale di una proteina determina la sua funzione. Questa tesi descrive una suite di metodi per il problema del riconoscimento di siti di legame di proteine, basati su una rappresentazione a spin-images della supercie molecolare. Una procedura per l'identicazione di cavita' integrata con una procedura per il riconoscimento di regioni simili in due proteine, e applicata al confronto delle cavita' di due proteine, il confronto all-to-all pairwise di un insieme di cavita', e il riconoscimento di siti di legame multipli in una cavita'. I metodi presentato possono essere usati per analizzare vaste collezioni di proteine
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
