Summary

Subtilisins have dominated detergent proteases for 20 years. Future enzymes may use new backbones or improved subtilisins, balancing performance with production viability.

Area of Science:

  • Enzymology
  • Biotechnology
  • Industrial Microbiology

Background:

  • Subtilisins have been extensively developed as detergent proteases over the last two decades using advanced enzyme technology.
  • Despite significant research, the number of characterized subtilisin variants entering the market remains limited.

Purpose of the Study:

  • To explore the future trajectory of detergent protease development.
  • To question whether next-generation proteases will utilize novel protein backbones or further refined subtilisin variants.

Main Methods:

  • Review of enzyme technology applications in protease development.
  • Analysis of factors influencing market entry of new enzymes.
  • Consideration of rational design, directed evolution, and natural diversity exploitation.

Main Results:

  • A continuous flow of new and improved subtilisin enzymes has been generated.
  • There is a discrepancy between the number of identified/characterized enzymes and those successfully commercialized.

Conclusions:

  • The future of detergent proteases hinges on whether innovation will lead to new enzyme families or enhanced subtilisins.
  • Commercial success will depend on enzyme performance, fermentation yield, and compatibility with current production processes.
