L15 and L18e ribosomal proteins share a common structure consisting mainly of parallel beta sheets (beta-alpha-beta units) with a core of three turns of irregular (beta-beta-alpha)n superhelix [ 1 , 2 ]. This superfamily includes higher eukaryotic ribosomal 60S L27A, prokaryotic 50S L15, fungal mitochondrial L10, plant L27A, mitochondrial L15, chloroplast L18-3 proteins, 60S L18 from eukaryotes and 50S L18e from Archaea.
