Directed evolution and rational design were used to engineer a fungal laccase. This resulted in a highly active and stable enzyme, overcoming challenges with high redox potential laccases.

Area of Science:

  • Biocatalysis and enzyme engineering
  • Protein engineering of fungal enzymes

Background:

  • High redox potential laccases from white-rot fungi present engineering challenges.
  • Improving enzyme activity and expression is crucial for industrial applications.

Discussion:

  • Directed evolution successfully enhanced laccase activity and expression.
  • Rational design was necessary to restore thermostability lost during directed evolution.

Key Insights:

  • A combined directed evolution and rational design approach yields highly active and stable fungal laccases.
  • Overcoming recalcitrance in engineering high redox potential laccases is achievable.

Outlook:

  • This engineered laccase has potential applications in various industrial processes.
