Currently, commercial plant peroxidases are all native and are isolated from plants such as horseradish and soybean. No recombinant plant peroxidase products have been available on the commercial market. The gene encoding peroxidase was cloned from windmill palm tree leaves. The codon-optimized gene
High peroxidase activity was demonstrated to be present in the leaf of several species of cold-resistant palms. Histochemical studies of the leaf of windmill palm tree (Trachycarpus fortunei) showed the peroxidase activity to be localized in hypoderma, epidermis, cell walls, and conducting bundles.
Palm peroxidases are extremely stable and have uncommon substrate specificity. This study was designed to fill in the knowledge gap about the structures of a peroxidase from the windmill palm tree Trachycarpus fortunei. The complete amino acid sequence and partial glycosylation were determined by
Plant secretory (Class III) peroxidases are redox enzymes that rely on N-glycosylation for full enzyme activity and stability. Peroxidases from palm tree leaves comprise the most stable and active plant peroxidases characterized to date. Herein, site-specific glycosylation and microheterogeneity of
Plant secretory peroxidases are valuable commercial enzymes. The windmill palm tree Trachycarpus fortunei produces one of the most stable and fastest peroxidases (WPTP) characterized to date; however, an economical source is needed. Pichia pastoris has been used as an expression system for WPTP and
