Structure of an Arabidopsis Tc1/Mariner-like transposon. (A) Similarities between TIRs and TSDs (underlined) of an Arabidopsis MLE I member and Tc1/Mariner-like elements Pogo (Drosophila, gi 8354) and Tigger (human, gi 2226003). (B) Putative transposase for the Arabidopsis MLE I (gi 4262216) aligned with transposases from Drosophila melanogaster PogoR11 (gi 2133672) and from human Tigger1 (gi 2226004). Amino acid residues are shaded based on the level of structural and functional similarities. Residues conserved between three or two sequences are shaded black and gray, respectively. The arrow (⇑) indicates the predicted start of the Arabidopsis MLE I ORF as annotated in GenBank. The first methionine of the Arabidopsis MLE I transposase was inferred from the reading frame and sequence similarity with the human Tigger1 element. The stop (*) was introduced by a single nucleotide substitution (at position 85709 in gi 4262209) from GAG (glutamine) to TAG (stop).
