A database of 926 (alpha + beta)-proteins and (alpha + beta)-domains containing abCd-units (among them 401 are nonhomologous) has been compiled from the Protein Data Bank (total 2636 PDB entries). A novel structural tree for this structural class of proteins that is composed of 286 possible polypeptide chain folds has been constructed. The structural classification of (alpha + beta)-proteins containing abCd-unit based on the structural tree has been developed. Both the database and the structural tree are accessible at the web-site (http://strees.protres.ru/).
