Building Better Enzymes - By Breaking Them Down
Enzymes are essential proteins that catalyze biochemical reactions in living organisms. They are used in various industries, including food, pharmaceuticals, and biofuels. However, enzymes have limitations, such as low stability and activity under harsh conditions. Scientists have been working on improving enzymes by breaking them down and rebuilding them into better versions. In this article, we will explore the process of building better enzymes by breaking them down.
What are Enzymes?
Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are made up of amino acids and are specific to a particular reaction or substrate. Enzymes can be found in all living cells and are involved in various metabolic processes, such as digestion, respiration, and DNA replication.
Limitations of Enzymes
Despite their importance, enzymes have limitations that hinder their use in various industries. For example, enzymes can be unstable under harsh conditions such as high temperature or pH. They can also be expensive to produce and may not be efficient enough for industrial applications.
Breaking Down Enzymes
To improve the efficiency of enzymes, scientists have been breaking them down into smaller fragments called peptides. Peptides are easier to produce and can be modified to enhance their stability and activity. By breaking down enzymes into peptides, scientists can identify the specific regions responsible for their function and modify them to improve their performance.
Rebuilding Better Enzymes
Once the peptides have been identified, scientists can rebuild them into better versions of the original enzyme. This process is called directed evolution and involves creating mutations in the peptide sequence to enhance its activity or stability. The mutated peptides are then screened for improved performance until a better version of the enzyme is obtained.
Applications of Improved Enzymes
Improved enzymes have various applications in different industries. For example, they can be used to produce biofuels from renewable sources such as corn and sugarcane. They can also be used in the food industry to improve the texture and flavor of products. In the pharmaceutical industry, improved enzymes can be used to develop new drugs or improve the efficacy of existing ones.
Conclusion
Enzymes are essential proteins that catalyze biochemical reactions in living organisms. However, they have limitations that hinder their use in various industries. Scientists have been breaking down enzymes into peptides and rebuilding them into better versions through directed evolution. Improved enzymes have various applications in different industries and can help to address some of the challenges faced by these industries.
