Abstract

Comparison of structures of homological proteins often helps to understand functionally significant features of these structures. This concerns not only structures of separate protein chains, but also structures of macromolecular complexes. In particular, a comparison of complexes of homologous proteins with DNA is significant for analysis of the recognition of DNA by proteins. We present program LCore for detecting geometrical cores of a family of structures; a geometrical core is a set of amino acid residues and nucleotides that disposed similarly in all structures of the family. We describe the algorithm of the program, its web interface, and an example of its application to analysis of complexes of homeodomains with DNA.
