Optimizing Biocatalysts for Industrial Performance

Enzyme engineering is crucial for overcoming the limitations of naturally occurring enzymes, which are often not suitable for harsh industrial conditions (high temperature, extreme pH or organic solvents). Our approach integrates computational design (rational or semi-rational) with high-throughput screening of large variant libraries. This ensures a systematic exploration of sequence space to identify mutants with superior catalytic properties. Whether you require a hyper-stable enzyme for continuous flow reactors or a highly specific enzyme to synthesize chiral compounds, our services provide the tailored biocatalytic solutions needed to drive efficiency and sustainability in chemical processes.

FAQs about Enzyme Engineering Services

Still have questions?

What properties of an enzyme can be engineered?

We can engineer catalytic efficiency (kcat/Km), stability (thermostability and solvent tolerance), substrate specificity, enantioselectivity, and cofactor preference.

What is the difference between rational design and directed evolution?

Rational design is structure-guided, introducing specific mutations based on computational prediction. Directed evolution, including Enzyme Directed Evolution, relies on cycles of random mutagenesis and high-throughput screening to mimic natural evolution, often leading to unexpected and highly beneficial mutations.

Do you offer high-throughput screening for enzyme libraries?

Yes. Our service includes the development and execution of tailored, high-throughput assays capable of screening thousands of variants from the Enzyme Library Construction to rapidly identify improved candidates.

Can you improve enzyme stability for industrial use?

Absolutely. We employ Enzyme Stabilization techniques through genetic modification and can provide enzyme formulation and Enzyme Immobilization services to enhance robustness and reusability.

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.
