Bridging Rational Design and Directed Evolution

Enzyme engineering is a multidisciplinary field focused on improving or altering the functions of natural enzymes for practical utility. Our platform offers a balanced approach, employing Rational Design when structural information is available to precisely guide mutations, and utilizing Directed Evolution when structural guidance is limited, relying on high-throughput screening of massive genetic diversity. For entirely new functions, our De Novo Design capabilities allow us to construct functional proteins from scratch. This integrated strategy ensures that whether you need to subtly adjust stability, drastically alter substrate specificity, or invent a new catalytic capability, we possess the tools and expertise to deliver customized, optimized enzymes for your specific biomanufacturing or therapeutic application.

FAQs about Enzyme Engineering and Optimization

Still have questions?

What is the difference between Rational Design and Directed Evolution?

Rational Design is knowledge-driven, relying on structural and biochemical data to predict specific beneficial mutations. Directed Evolution is blind, mimicking natural selection by screening vast numbers of randomly generated mutants to find the best performers.

Which approach is better for optimizing enzyme stability?

Often, a combination is best. Rational design can introduce known stabilizing elements (like disulfide bonds or optimized salt bridges), while directed evolution can find subtle, synergistic mutations that significantly enhance stability.

What is De Novo Enzyme Design used for?

De Novo Design is used to create enzymes from scratch to catalyze non-natural reactions or to serve as highly robust, minimal scaffolds for future engineering, especially when no suitable native enzyme exists.

How do you handle the problem of cofactor dependence in multi-enzyme cascades?

We integrate a dedicated, efficient cofactor regeneration system (e.g., using formate dehydrogenase for NAD(P)H) into the cascade, ensuring the required cofactor is continuously recycled, minimizing input costs.

How much does Metabolic Engineering services cost?

The cost of Metabolic Engineering services depends on the project scope, complexity of the target compound, the host organism chosen, and the required yield optimization. We provide customized quotes after a detailed discussion of your specific research objectives.

Do your engineered strains meet regulatory standards?

We adhere to high quality control standards in all strain construction and optimization processes. While we do not handle final regulatory approval, our detailed documentation and compliance with best laboratory practices ensure your engineered strains are prepared for necessary regulatory filings (e.g., GRAS, FDA).

What to look for when selecting the best gene editing service?

We provide various gene editing services such as CRISPR-sgRNA library generation, stable transformation cell line generation, gene knockout cell line generation, and gene point mutation cell line generation. Users are free to select the type of service that suits their research.

Does gene editing allow customisability?

Yes, we offer very customised gene editing solutions such as AAV vector capsid directed evolution, mRNA vector gene delivery, library creation, promoter evolution and screening, etc.

What is the process for keeping data private and confidential?

We adhere to the data privacy policy completely, and all customer data and experimental data are kept confidential.
