AB  - Lignin peroxidase (LiP) is a heme-containing oxidoreductase that oxidizes structurally diverse substrates in an H2O2-dependent manner. Its ability to oxidize many pollutants makes it suitable for bioremediation applications and an ideal candidate for optimization by mutagenesis and selection. In order to increase oxidative stability of LiP we generated a random mutagenesis library comprising 106 mutated LiP genes and screened for expressed enzymes with higher than wild-type activity after incubation in 30 mM H2O2 by flow cytometry with fluorescein-tyramide as a substrate. To preserve the genotype-phenotype connection, the LiP mutants were displayed on the yeast cell surface. Two rounds of sorting were performed, recovered colonies were then screened in microtiter plates, and activity analysis revealed a significant increase in the percentage of cells expressing LiP variants with higher oxidative stability than wtLiP. Two rounds of sorting increased the proportion of more-stable variants from 1.4% in the original library to 52.3%. The most stable variants after two rounds of sorting featured between two and four mutations and retained up to 80% of initial activity after 1 h incubation in 30 mM H2O2. We for the first-time applied flow cytometry for screening of any ligninolytic peroxidase library. Obtained results suggest that developed system may be applied for improvement of industrially important characteristics of lignin peroxidase.

AB  - Pleurotus eryngii wild-type versatile peroxidase (wtVP) oxidizes structurally diverse substrates in an H2O2-dependent manner, but its ability to oxidize many pollutants is limited by suicidal enzyme inactivation in the presence of excess H2O2. To address this drawback, we generated random mutagenesis libraries containing 3 × 106 mutated VP genes and screened for enzymes with higher oxidative stability expressed on the surface of yeast cells. This was achieved by flow cytometry using the substrate fluorescein tyramide. After two rounds of sorting, the percentage of cells expressing variants with improved oxidative stability had increased from 1 % to 56 %. The most stable variants featured 3–5 amino acid substitutions and retained up to 70 % of their initial activity after incubation for 1 h in 30 mM H2O2 (conditions that completely inactivate wtVP). Selected variants were extracted from yeast cell walls and purified for kinetic characterization. We also prepared yeast cell walls with wtVP and the three most stable VP variants for multiple cycles of azo dye (Reactive black 5) degradation. After 10 cycles of 12 h, two of the variants retained more than 97 % of their initial activity, whereas the activity of wtVP declined by ∼30 %. These results confirm that our high-throughput screening system can improve the oxidative stability of versatile peroxidase, providing a source of novel enzymes for remediation applications.
