Enzyme Structural Bioinformatics and Modeling Services

CD Biosynsis offers advanced Enzyme Structural Bioinformatics services, providing deep computational insights into enzyme mechanism, stability, and function based on three-dimensional structures. By employing homology modeling, molecular dynamics (MD) simulations, and quantum mechanics/molecular mechanics (QM/MM) calculations, we accurately predict key enzymatic properties that guide rational design and optimization. Our services focus on understanding the enzyme-substrate complex, predicting substrate specificity, identifying allosteric sites, and calculating the effects of mutations on stability and kinetics. This powerful predictive capability, which includes Active Site Prediction, Substrate Binding Simulation, and Interaction Modeling, is essential for accelerating Enzyme Engineering and the discovery of highly efficient biocatalysts for industrial applications.

Decoding Enzyme Function Through 3D Structure

Structural bioinformatics provides the blueprints for manipulating enzyme function. By generating high-quality predicted structures (homology models) or analyzing existing crystal structures, we can visualize the molecular interactions governing catalysis. This is crucial for rational design, as it allows us to precisely identify residues within the active site or on the surface that can be mutated to improve properties like activity, thermostability, or selectivity. Our molecular modeling techniques simulate the dynamic behavior of the enzyme and its substrate, offering a true-to-life understanding of the catalytic cycle and informing the most promising targets for experimental Enzyme Engineering.

FAQs about Enzyme Structural Bioinformatics Services

Still have questions?

What is the primary input required for your service?

We primarily require the amino acid sequence of your target enzyme. If available, any existing crystal structure (PDB file) or kinetic data is also helpful.

What is the difference between Active Site Prediction and Interaction Modeling?

Enzyme Active Site Prediction & Analysis Service focuses on locating and characterizing the catalytic pocket itself. Enzyme Substrate Interaction Modeling Service specifically analyzes how a particular substrate docks into that site and the forces governing binding affinity and specificity.

Can you predict the effect of a mutation on enzyme stability?

Yes. We use computational methods to calculate the change in folding free energy (ΔΔG) resulting from an amino acid substitution, providing quantitative prediction of stability changes.

Do you use molecular dynamics (MD) simulations?

Yes. MD simulations are integral to our services, especially for the Enzyme Substrate Binding & Pathway Simulation Service, as they allow us to observe the dynamic movement of the enzyme and substrate over time, capturing flexibility essential for catalysis.

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.
