Knowledge discovery in molecular biology ldentifying structural regularities in proteins

摘要

In recent years, there has been an explosive amount of molecular biology information obtained and deposited in various databases. Identifying and interpreting interesting patterns from this massive amount of information has be- come an essential component in directing further molecular biology research. The goal of this research is to discover Structural regularities in protein sequences by applying the SUBDUE discovery system to databases found in the Brookhaven Protein Data Bank. In this paper we discuss issues relevant to this application including data preparation and representation. We report on the results of applying SUBDUE to several classes of protein structures and discuss the potential significance of these results in the study of proteins.
