QuESt – short for Quality Enzyme Solutions – is our all-in-one solution to give your enzymes the competitive advantage. We can enhance every property of your enzyme, including enzymatic activity, thermal resilience, solvent stability, pH resistance, substrate specificity product spectrum, removing inhibitory effects and more. Our track record spans more than 30 enzymes and assays including lipases, proteases, polymerases, laccases, monooxygenases, reductases, sugar isomerases, cellulases, phytases, pectinases, glucose oxidases, amylases and alcohol dehydrogenases that are expressed and screened in our four expression platforms E. coli, B. subtilis, S. cerevisiae and P. pastoris.
QuESt employs our protein engineering strategy “KnowVolution” – a knowledge-gaining directed enzyme evolution. KnowVolution is a combined approach of random and rational enzyme evolution, compensating the disadvantages of purely random or purely rational (computational) evolution strategies. As a result, we achieved both a high cost efficiency and increased success chances.
Each of our projects is tailored to your enzyme, your application and your needs. We claim to be as flexible as research projects allow with optional project time-outs in which you can test our evolved variants as well as milestones to report and assess the progress.
Find below two success stories of our QuESt service where we applied our advanced Directed Evolution strategy “KnowVolution” to engineer superior enzyme variants.
Over the course of 11 months at 1 FTE, the specific activity of the evolved polymerase variants were improved by a factor of 40 compared to the wild type polymerase.
Benefits to client:
Over the course of 11 months at 1 FTE, the long-term stability of the final variant was enhanced by more than 400% compared to the best performing variant of the client.
