Peroxidase activity can dictate the in vitro lignin dehydrogenative polymer structure

We assessed the influence of the horseradish peroxidase/coniferyl alcohol ratio on the Zutropf and Zulauf DHP synthesis. This parameter governs the polymerization degree, the β-O-4 content and the frequency of coniferyl alcohol end-groups. Lignin biosynthesis and structure could thus be partially controlled by the peroxidase concentration and availability.
