Is horseradish peroxidase a ligninolytic enzyme?
Structural modifications of spruce liginins catalyzed by plant horseradish peroxidase (HRP) were studied. Changes in lignin structure were characterized by monomeric composition determination and hydrodynamic property analysis. Results show that HRP modifies lignin monomeric composition without alteration of polymer gel permeation pattern. This indicates that HRP and LiP have similar but different biodegradative effects.
