Custom Unnatural Protein Engineering Service

Creative Biolabs specializes in engineering services dedicated to creating synthetic proteins. Our partnership commitment extends to protein-related research through our extensive protein engineering services including unnatural peptide synthesis and recombinant unnatural protein preparation.

The functional properties of living systems rely mainly on proteins which consist of 20 natural amino acids across all organisms, and the attributes of proteins in terms of physical and chemical characteristics depend on the side chains found within their amino acid components. In this case, the integration of amino acids with side chains that have unique physicochemical characteristics like keto groups, crosslinkers, or NMR probe groups becomes highly beneficial for specialized applications. Unlike natural outcomes, the intentional integration of unconventional amino acids with unique functional side chains stands as a potent method for creating engineered proteins and new organism capabilities beyond what nature provides. In vivo protein structure and function studies now benefit from the valuable applications of this service.

Competitive Advantages

Unnatural proteins offer multiple competitive advantages compared to their natural counterparts. The competitive edge of unnatural proteins comes from their capability to extend the genetic code and create functionalities that surpass natural limitations, such as:

Enhanced Functionality: Enables the incorporation of novel features beyond natural protein capabilities, including but not limited to: integration of fluorescent probes for real-time monitoring; adding chemical handles for precise site-directed conjugation of therapeutic agents or polymers; and introducing photocaged groups for light-controlled protein activity.
Improved Stability and Pharmacokinetics: Enhances protein stability through the introduction of structural cross-links or optimized hydrophobic interactions, or modify pharmacokinetic properties by extending circulatory half-life to improve the therapeutic efficacy of proteins in systemic applications.
Novel Therapeutic Applications: Creates next-generation therapeutic agents with improved efficacy and reduced side effects.
Expanded Research Capabilities: Provides powerful tools for studying protein structure-function relationships, empowering researchers to dissect complex biological mechanisms with exceptional precision and molecular resolution.
Creation of Novel Biomaterials: Enables the development of advanced protein-based biomaterials featuring unique characteristics, such as superior mechanical resilience and stimulus-responsive behaviors, for diverse biomedical and biotechnological applications.

Technology

Our services include custom protein engineering solutions where we design and synthesize modified peptides or proteins according to your particular needs. A range of biochemical and biophysical methods can be used to validate the properties of these altered proteins, including but not limited to:

Gel Electrophoresis: Evaluating protein purity and characterizing aggregation states.
Binding Ability Test: Evaluating whether the interactions between the modified protein and its ligands, substrates, or other interacting molecules have been altered.
Mass Spectrometry: Investigating post-translational modifications and elucidating alterations in protein structure and molecular weight.
X-ray Crystallography: Revealing how external factors modulate the protein's 3D structure.
Enzyme Activity Evaluation: Assessing the activity of modified enzyme proteins by measuring catalytic rates, substrate specificity, and inhibition profiles.
Fluorescence Spectroscopy: Studying protein folding, conformational dynamics, and molecular interactions in proteins with modified fluorescent properties.
