The VPs (versatile peroxidases) secreted by white-rot fungi are involved in the natural decay of lignin. In the present study, a fusion gene containing the VP from Pleurotus eryngii was subjected to six rounds of directed evolution, achieving a level of secretion in Saccharomyces cerevisiae (21 mg/l) as yet unseen for any ligninolytic peroxidase. The evolved variant for expression harboured four mutations and increased its total VP activity 129-fold. The signal leader processing by the STE13 protease at the Golgi compartment changed as a consequence of overexpression, retaining the additional N-terminal sequence Glu-Ala-Glu-Ala that enhanced secretion. The engineered N-terminally truncated variant displayed similar biochemical properties to those of the non-truncated counterpart in terms of kinetics, stability and spectroscopic features. Additional cycles of evolution raised the T₅₀ 8°C and significantly increased the enzyme's stability at alkaline pHs. In addition, the K_m for H₂O₂ was enhanced up to 15-fold while the catalytic efficiency was maintained, and there was an improvement in peroxide stability (with half-lives for H₂O₂ of 43 min at a H₂O₂/enzyme molar ratio of 4000:1). Overall, the directed evolution approach described provides a set of strategies for selecting VPs with improvements in secretion, activity and stability.
