Researchers discovered novel thermostable hydrolases from extreme environments using advanced screening methods. These enzymes offer new possibilities for industrial processes and environmental applications.
Area of Science:
- Enzyme discovery and engineering
- Biotechnology
- Environmental microbiology
Background:
- Novel hydrolases from extreme environments are valuable for industrial applications.
- Existing enzymes and processes can be improved by thermostable hydrolases.
- Systematic screening methods are needed for discovering enzymes with desired functions.
Purpose of the Study:
- To develop and integrate technologies for discovering, identifying, and characterizing novel thermostable hydrolases.
- To mine hot terrestrial and marine environments for new enzymes.
- To establish new tools for enzyme discovery and functional screening.
Main Methods:
- Mining hot springs for environmental samples and enrichment cultures.
- High-throughput sequencing (metagenomes, genomes, transcriptomes).
- Bioinformatics analysis using the Anastasia platform and whole-cell bioreporter-based functional screening.
Main Results:
- Hundreds of samples and thousands of cultures were generated.
- 15 hot spring metagenomes and several isolate genomes/transcriptomes were sequenced.
- Approximately 100 potential novel hydrolases were identified, with over a dozen characterized (e.g., carboxylesterases, cellulases).
Conclusions:
- The HotZyme project successfully developed a workflow for discovering and characterizing novel thermostable hydrolases.
- The identified enzymes possess valuable biochemical and structural properties for various applications.
- The generated data and samples provide a foundation for future enzyme discovery.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
