Mature peroxidase protein sequence comparison. The predicted protein sequences encoded by zucchini APRX clone (this study), two cucumber peroxidase cDNAs, Csprepera and Cspreper (Rasmussen et al., 1995), and a tobacco peroxidase cDNA, Ntpxdlf (Lagrimini et al., 1987), are shown. The alignment was created with the PileUp program and sequence homology was determined with the PrettyPlot program (both programs from Genetics Computer Group).
