title: [Structural similarity of the active sites of major histocompatibility complex class I proteins and ubiquitin].
abstract: With the help of a new method of protein primary structures analysis, i.e. CAACRA (comparative amino acid codon root analysis) a marked structural similarity of the MHC class I protein active sites and ubiquitin alpha-helix has been revealed. Using the CAACRA a periodicity of ubiquitin primary structure has been shown. Ubiquitin molecule consists of 4 repeat units.
