Researchers engineered a hyperstable enzyme, a thermolysin-like protease (TLP-ste), through targeted mutations. This enhanced enzyme functions at 100°C and retains activity at 37°C, offering a robust biocatalyst.

Area of Science:

  • Biochemistry
  • Enzymology
  • Protein Engineering

Background:

  • Enzymes from extremophiles offer insights into hyperstability.
  • Developing hyperstable biocatalysts is a key research goal.

Purpose of the Study:

  • To engineer a hyperstable enzyme from a moderately stable precursor.
  • To investigate the structural basis of enzyme hyperstability through mutagenesis.

Main Methods:

  • Site-directed mutagenesis of a thermolysin-like protease (TLP-ste).
  • Incorporation of mutations from naturally thermostable variants.
  • Rational design of mutations to enhance stability.

Main Results:

  • An 8-fold mutant TLP-ste enzyme exhibiting hyperstability was created.

  • The mutant enzyme functions effectively at 100°C and in denaturing conditions.
  • The engineered enzyme maintained wild-type-like activity at 37°C, unlike many natural hyperstable enzymes.
  • Conclusions:

    • Limited, strategic mutations can confer hyperstability to enzymes.
    • Engineered hyperstable enzymes can possess broad operational temperature ranges.
    • This approach yields robust biocatalysts with retained functionality.
