Characteristics of Pangu transposons. a Sequence alignments for Pangu_CGig family. The terminal inverted repeats (TIRs) and flanking sequences (10 bp) are shown. b Two examples of alignments of the flanking sequences of Pangu_CGig insertions with a paralogous sequences found within the same genome but devoid of the transposon. The TIRs of the element are underlined. c Structure of Pangu_CGig. Black triangles and solid black boxes represent the TIRs and ORFs, respectively, and the position of the DDE triad is shown. d Predicted secondary structure of the DDE motif-containing transposase of the Pangu_CGig. The DDE triads is marked with red triangles below the sequence
