In this dissertation, we describe two projects on the analysis ofprotein interactions using structural information. The focus of the rst is to charac-terize and classify di erent types of interactions. We discriminate between biologicalobligate and biological non-obligate interactions, and crystal packing contacts. Tothis end, we de ned six interface properties and used them to compare the threetypes of interactions in a hand-curated dataset. Based on the analysis, a classi- er, named NOXclass, was constructed using a support vector machine algorithmin order to generate predictions of interaction types. NOXclass was tested on anon-redundant dataset of 243 protein-protein interactions and reaches an accuracyof 91.8%.
