The diversity of the PPT/3'LTR junction of classic Ty1/copia retrotransposons. Alignment of the conserved Sirevirus PPT/3'LTR junction to the respective region of classic Ty1/copia retrotransposons. Underlined bases represent the 3' terminus of the IR left arm, and nucleotides shaded in black indicate the beginning of the 3'LTR. The location of the IR left arm is universally conserved in all Pseudoviridae.
