Multiple sequence alignments of key domains of the nucleocapsid protein and protease of the Sinbad retrotransposon and related elements. A. Amino acid alignment of the Cys-His box region of the nucleocapsid protein of Sinbad and five other Pao-like elements. Sinbad shares the triple Cys-His box motif of these elements (underlined). B. Amino acid alignment of the protease domain of Sinbad and five other Pao-like elements. Sinbad shares the LLDXG + LIG protease motifs conserved in Pao-like elements (underlined). Identical and chemically similar residues are boxed and shaded.
