Abstract

Large amount of structural data is available about individual protein families originating from different organisms, binding various ligands and containing diverse mutations. Secondary structure elements (SSEs) are often characteristic for a protein family and participate in the formation of protein fold. Composition and organization of SSEs can help to identify similarities and differences between proteins within protein families. To utilize the SSEs for research on protein families, we should be able to easily and automatically link and intercompare corresponding SSEs within one protein family. Specifically, the corresponding SSEs should have the same name (annotation) and we need a transparent and coherent schema of their localization in the protein structures, retaining structural information (i.e., minimize a deviation between SSEs distances in 2D schema and in 3D structure). We developed a tool set [1] fulfilling these requirements. It was successfully tested on all CATH families and its utilization in Protein Data Bank and CATH is planned.
