Fig. 4From: Experimental and theoretical insights into the effects of pH on catalysis of bond-cleavage by the lignin peroxidase isozyme H8 from Phanerochaete chrysosporiumRelative Gibbs free energy required for breaking various bond types in lignin via the cationic radical intermediate (left) and the phenoxy radical intermediate (right). Gibbs free energy was normalized to reactants at each reaction stepBack to article page
