Enzyme discovery with bioinformatic tools and HT techniquesFigure 1. Main Strategies for Novel Enzymes Discovery
(Bioprocess and Biosystems Engineering 2017)

Enzymes have found applications as biocatalysts with high efficiency and selectivity in manifold fields of chemistry and biology. Yet, only a small portion of natural enzymes have been exploited industrially. Traditional strategies to isolate novel enzymes from wild-type strains, including DNA extraction, heterologous protein expression and a generic assay, are usually time-consuming and with limited sensitivity. Creative Enzymes has built professional high-throughput platforms for enzyme discovery with significant advantages:

  • Advanced bioinformatic tools and genome mining approaches
  • Metagenomic libraries construction
  • High throughput screening, analysis and characterization
  • Statistical design of experiments
  • Seamless separation and purification
  • Enzyme de novo identification

Strategies for enzyme discovery from nature can be categorized into two main methodologies, which could be combined for best results. The first involves direct detection of the desired enzymatic activity. Based on next-generation sequencing (NGS) methods, Creative Enzymes constructs metagenomic libraries and develops high-throughput screening for enzymatic activity. The second strategy involves function prediction and in silico screening. Creative Enzymes applies genome mining approaches for enzyme discovery based on similarities of their DNA sequences or 3D structures to those of known activity. We also investigate interactions among different enzymes in case a series of enzymes need to stay in the system for the best performance.

Creative Enzymes conducts structure and activity characterization for identification of novel enzymes. We offer services on demand, including primary structure determination, disulfide bond analysis, and 3D structure determination.

Enzyme discovery represents a growing field with many possible applications including animal feed, biocatalysts, pharmaceuticals and chemical processing. Creative Enzymes has tight connections in both academia and industry, and thus has accumulated rich experience to provide the most advanced solutions for our customers.

Q1: Can I use an “existing” protocol for my enzyme assay?

It is to be noted that all enzymes reach their optimum activity under different conditions, whereas in a high-throughput screening, one single reaction condition is often used. As a result, the differences in the activity levels of enzymes may be true only in the current condition and cannot be used for quantitative comparison. Another challenge that frequently troubles researchers is that detection of formation of the product or the consumption of the substrate could be strongly disturbed by other ingredients in the reaction matrix, such as inactive solutes or other enzymes. In such cases, the signal to noise ratio must be considered for accurate measurement. Proper selection of the detection method and parameters often gives solutions to such problems.

Creative Enzymes has been a pioneer in the enzymology assay area. We served customers to optimize a product or to set a solid foundation for further research. You can find any level and scale of enzymology assays available at Creative Enzymes.

Q1: Why should I modify my enzyme?

The existing enzymes can go through certain structural alterations and hence, the resulted function and catalytic activity allow new catalyzed pathways of reactions. In addition, modification could also enhance biochemical properties, pharmacokinetics, and stability. Enzymes can be physically modified in immobilization and encapsulation. Researchers also extent naturally occurring chemical reactions of enzymes to other chemicals such as polymers, aldehydes, imidoesters and anhydrides, to give enzymes more divers properties. In addition, chemists have developed a large set of reactions that label the enzymes through post-expression modifications. Many properties of an enzyme may be modified to achieve the objective:

With advanced technologies and instruments, we develop and prepare enzyme conjugates not only by innovative conjugation reactions, but also through improvement in protein expression, isolation and purification, and validation and characterization. We provide conjugation services for enzyme production based on customer requirements for various studies and applications, including immunosorbent assays (ELISAs), western blotting, immunostaining, and biosensors.

Enzyme conjugates with different moelcules.Figure 1 Protein conjugation with other molecules.
(Chemical Reviews 2018)

Enzymes are used as signal generating reporters when conjugating to other molecules. Various reporter enzymes, such as horseradish peroxidase (HRP), Alkaline phosphatase (AP) and many others, can be attached to antibodies, proteins and nucleic acid for applications in immunoassays and biosensors. Also, enzymes can be modified with conjugation for desired properties and functions, especially stability. In pharmaceutical applications, these conjugates can be used as smart “vehicles” for drug delivery. To meet various requirements from customers, Creative Enzymes has built professional and updated enzyme conjugation platforms with plenty of advantages:

  • Nearly 1:1 ratio of enzyme to interested target
  • Optimized sample preparation and conjugation
  • High product yield and purity
  • Strict validation and characterization
  • Scale-up production up to kilograms

Enzymes can be conjugated with other molecules via chemical, enzymatic, or chemoenzymatic formation of new covalent bonds. Usually, small linkers such as glutaraldehyde or protein tags are used in these conjugations. Those enzyme conjugates to one or multiple types of molecules based on applications in different fields. For immunoassays and other related applications, Creative Enzymes provides “activated” enzymes in purified, activated, and kit formats for easy conjugation. For specific applications in pharmaceutical/non-pharmaceutical industry, Creative Enzymes offers desired enzyme conjugates with developed purification and scale-up procedures. Creative Enzymes also has the ability to conduct characterization and validation of target conjugates product.

Enzyme conjugation represents a booming market in medical diagnostics, gene expression analysis, detection of infectious diseases and biological warfare agents among others. Creative Enzymes has tight connections in both academia and industry, and thus has accumulated much experience to provide the latest solutions for our customers.

Creative Enzymes has worked closely with the customers to meet their needs in this last step of delivering an enzyme product. With all the expertise and experience in house, we are confident to solve any challenge you may have during commercializing the enzyme product.

Q1: Do I need enzyme stabilization & formulation as part of product development?

A: Enzyme formulation is one last and important step in commercializing an enzyme containing product. Nonetheless, the step has not yet received enough notice for its key role in effectively delivering the intended performance of the product. The main purpose of formulation is to preserve the enzyme in a ready-to-use form until consumed by the customer. Many companies spent a significant amount of resource and time on developing and testing the new enzyme product in details to deliver perfect biochemistry. However, final customers are only interested in the safety, stability, and aesthetics of the products on the shelf. Therefore, the product is only completed when it goes into the final package. At Creative Enzymes, we understand the importance of stable enzyme activity and will help you keep the enzymes stable during long-term storage. We also perform proper aging tests that predict the shelf life of an enzyme product using acceleration tests and kinetic models. In the end, we are happy to develop and optimize the product formulation for a specific enzyme.
