Engineers Create Bacteria That Can Synthesize an Unnatural Amino Acid
Scientists have made a breakthrough in the field of synthetic biology by engineering bacteria that can produce an unnatural amino acid. This achievement has significant implications for the development of new drugs and materials.
What Are Amino Acids?
Amino acids are the building blocks of proteins, which are essential for life. There are 20 naturally occurring amino acids that are used to make proteins in all living organisms. However, scientists have been interested in creating new amino acids that do not occur naturally in order to expand the range of proteins that can be made.
The Importance of Unnatural Amino Acids
Unnatural amino acids have a range of potential applications. For example, they can be used to create proteins with new functions or properties, such as increased stability or activity. This could lead to the development of new drugs or materials with unique properties.
How Were the Bacteria Engineered?
The team of engineers responsible for this breakthrough used a technique called "directed evolution" to engineer bacteria that could produce an unnatural amino acid. They started with a strain of E. coli bacteria that had been modified to require the unnatural amino acid in order to survive.
The researchers then used a process called "error-prone PCR" to introduce mutations into the genes responsible for producing the natural amino acid that was being replaced. They then screened thousands of bacterial colonies to identify those that were able to produce the desired unnatural amino acid.
What Are the Implications of This Breakthrough?
This breakthrough has significant implications for the field of synthetic biology. It demonstrates that it is possible to engineer bacteria to produce new and useful compounds, which could lead to the development of new drugs and materials.
In addition, this research could pave the way for other advances in synthetic biology, such as the creation of entirely new organisms with novel functions or properties.
Conclusion
The engineering of bacteria that can produce an unnatural amino acid is a significant achievement in the field of synthetic biology. This breakthrough has the potential to lead to the development of new drugs and materials with unique properties, and could pave the way for other advances in the field.
