This presentation examines the available in silico tools for protein structure and function prediction. It examines the major protein family databases (PROSITE, PRINTS, Pfam, etc.), and explores why tools like PSI-BLAST, while convenient and easy to use, may not always give optimal results. The presentation concludes with an analysis of 'expert' systems and integrated approaches (GeneQuiz, MAGPIE, InterPro, etc.), and dispels the commonly held notion that one database and/or one analysis tool is best.
