Figure 1From: Mutational analysis of highly conserved aspartate residues essential to the catalytic core of the piggyBac transposaseAlignment of piggyBac -related proteins. A BoxShade server alignment of the proteins listed in table 1. Residues aligning with piggyBac position 1–63 are shown. Only two piggyBac family proteins have been shown to catalyze transposition, these are indicated by bold face type and asterisks.Back to article page
