Protein Engineering & Directed Evolution

„Protein Engineering – also called Directed Evolution – is the way to unlock the vast potential of nature’s enzymes and thus bring benefits to products, people and the planet”

– David Schönauer, Managing Director

While enzymes are the foundation of basically all reactions in living organisms on the molecular level, nature did not evolve enzymes to be perfect biocatalysts and tolerate conditions present in industrial products and processes.

Directed enzyme evolution, also known as Protein Engineering, allows to adapt enzymes to these “un-natural” environments by introducing mutations on the gene level that results in improved properties and features of the resulting enzyme.

 

We are able to effectively optimize enzymes towards:

 

  • Higher activity/yield
  • Enhanced stability at high/low pH
  • Enhanced stability at high/low temperatures
  • Enhanced long-term stability
  • Increased organic solvent resistance
  • Improved specificity
  • Larger or narrowed substrate spectrum
  • Protease resistance
  • Decreased subsrate or product inhibition
  • Reduce sequence similarity with patented enzymes

Protein engineering as part of the QuESt-service

 

Protein Engineering is a central part of SeSaM-Biotech’s QuESt-service, our all-in-one package for Directed Enzyme Evolution. We evolve enzymes for every industry branch ranging from fine chemicals, pharmaceuticals, molecular biology, diagnostics and cosmetics over food, nutrition and beverages, feedstocks up to textiles, pulp and paper as well as biofuels.
