Substrate Profiling is a crucial part of enzyme research. It involves identifying the substrates where an enzyme can perform its activity. This process is essential for understanding the enzyme's function, its role in biological processes, and providing insight into life at a molecular level. This study can also contribute significantly to drug discovery and development by identifying potential therapeutic targets. Our services offer a thorough approach to enzyme substrate profiling. We aim to provide an analysis that not only identifies the substrates but also understands the enzyme's interaction with them. This approach gives a clearer picture of its role and potential applications.

| Application | Description |
|---|---|
| Drug Discovery | Substrate profiling plays a vital role in drug discovery processes by aiding in the identification of potential drug candidates and understanding their mechanism of action. It involves screening libraries of compounds against specific enzymes to identify substrates or inhibitors. This helps researchers in selecting lead compounds for further development and optimization of drug candidates. |
| Metabolic Engineering | Metabolic engineering aims to optimize cellular processes for the production of valuable compounds such as biofuels, pharmaceuticals, and chemicals. Substrate profiling assists in this endeavor by identifying key enzymes and substrates involved in metabolic pathways. This information is utilized to design and engineer efficient biocatalysts, leading to improved yields and productivity. |
| Biotechnology | Substrate profiling is fundamental in biotechnology for various applications such as characterizing enzyme activities, screening enzyme inhibitors, and developing biocatalysts for industrial processes. It provides valuable insights into enzyme-substrate interactions, enabling the design of enzymes with enhanced specificity, stability, and activity for specific biotechnological applications. |
| Environmental Monitoring | Environmental monitoring involves assessing the health and integrity of ecosystems and detecting environmental pollutants. Substrate profiling aids in this process by measuring enzyme activities in different environmental samples. Changes in enzyme activities can indicate environmental stressors, pollution levels, or ecological disturbances, providing valuable information for environmental management and conservation efforts. |
| Agriculture | In agriculture, substrate profiling is employed for understanding plant enzyme activities involved in various physiological processes such as nutrient uptake, defense mechanisms, and stress responses. By elucidating enzyme-substrate interactions, researchers can optimize agricultural practices, develop strategies for pest and disease management, and enhance crop yields and quality, contributing to sustainable agricultural production. |
To delve deeper into the substrate specificities of immunoproteasome (iP) and proteasome (cP), a comprehensive approach known as Multiplex Substrate Profiling by Mass Spectrometry (MSP-MS) is utilized in below figure. This innovative methodology employs a balanced mixture of 228 strategically selected 14-mer peptide substrates to provide an unbiased evaluation of protease substrate specificity. The procedure begins with the introduction of iP or cP to the peptide library. Subsequently, peptide cleavage products are identified using liquid chromatography-tandem mass spectrometry (LC-MS/MS) at various time intervals: 60, 120, 240, and 480 minutes. Only cleavage sites that appear in two biological replicates of each proteasome are considered. The findings reveal wide-ranging substrate specificity. The proteasomes show the ability to hydrolyze 391 (for iP) and 330 (for cP) distinct peptide bonds after 480 minutes of incubation, equivalent to 13.2% and 11.1% of the total cleavage sites in the library for iP and cP, respectively. By the 480-minute mark, saturation of new cleavage-site usage is evident, indicating the depletion of the most favored cleavage sites in the library. This observation underscores the capability of the MSP-MS assay to effectively detect the most prevailing cleavage events.
