Global Organization of All Known Proteins: Exploring the Sequence-Structure Mapping of Proteins

Keywords: sequence-structure mapping, clustering, protein families, protein classification, sequence and structure based metrics, geometry of proteins space

This research aims to find a globally consistent organization of all proteins, based on the existing measures of distance for protein sequences, and by combining structural information. This research focus on exploring the mapping from sequence space to structure space, exploring structure based metrics, and exploring high organization order in the space of all proteins. It makes essential use of recent developments in the theory of metric embedding and unsupervised learning, and of graph theoretic and algorithmic tools. The research also makes use of results obtained for sequence space. These results suggest the compression of sequence space into a smaller set of representative sequences, with a possible correspondence with the set of all known structures.

High organization order might be a necessity in the view of the constant flow of new biological information, we have been witnessing in recent years. This organization may give a global view (ìmapî) of the universe of all proteins. Such a global view would serve as a key tool for the analysis of proteins, reveal relationships among protein families and add some insights about the nature of new sequences. Moreover, by combining sequence as well as structure considerations, a new map of the proteins universe may take us one step closer to understanding the evolutionary aspect of protein creation mechanism.
