Fig. 2From: In silico-designed lignin peroxidase from Phanerochaete chrysosporium shows enhanced acid stability for depolymerization of ligninConversion of VA by native LiPH8 and its variants with introduction of a single salt bridge (a) and combined salt bridges (b). The oxidation reaction was carried out in 0.1 M BR buffer, pH 2.5 with 4 mM VA and 1 μM native LiPH8 or variants, in which H2O2 was fed at a rate of 150 μM/15 min at 25°CBack to article page
