AbstraktWith the rapid growth of public protein structure databases, computational techniques for storing as well as comparing proteins in an efficient manner are still in demand. Proteins play a major role in virtually all processes in life, and comparing their three-dimensional structures is essential to understanding the functional and evolutionary relationships between them. In this study, a novel approach to compute three-dimensional protein structure alignments by means of so-called EigenRank score profiles is proposed. These scores are obtained by utilizing the LeaderRank algorithm-a vertex centrality indexing scheme originally introduced to infer the opinion leading role of individual actors in social networks. The obtained EigenRank representation of a given structure is not just highly-specific, but can also be used to compute profile alignments from which three-dimensional structure alignments can be rapidly deduced. This technique thus could provide a tool to rapidly scan entire databases containing thousands of structures.
