Figure 2From: 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 64–160 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
