Ginger1 (for ' Gypsy INteGrasE Related 1') elements and transposases. (a) Schematic features of the Ginger1 DNA transposons. Target site duplications (TSDs) and target sequences preferences of the Ginger1 and Ginger2 groups are compared, which is based on the data of 112 Ginger1 elements from Hydra magnipapillata and 64 Ginger2 elements from Nematostella vectensis. (b-d) Alignment of Ginger1 and Gypsy integrases in the YPYY motif and the H2C2 zinc finger domain (b), the DDE core domain (c), and the GPY/F motif (d). (e) Alignment of the Ulp1 and plant homeodomain (PHD) domains in Ginger1 TPases, Mutator TPases and yeast protein 1EUV_A; the PHD domain is boxed. (f) Alignment of the ovarian tumor (OTU) domains of Ginger TPases, Helitron proteins, and yeast protein 3BY4_A.
