Forster lab
We work on protein synthesis, synthetic biology and drug discovery.
Popular science presentation
Proteins are the main active and structural molecules of life. They are synthesized from 20 different amino acids by a machine called the ribosome in a complicated process that is central to growth and indeed all of biology. Protein synthesis in bacteria is the major target of antibiotics, and antibiotic discovery has again become a major health research priority because of mounting antibiotic resistance. Protein synthesis is also fundamental to biomedical research and biotechnology (e.g. for synthesis of enzyme, hormone and antibody proteins). Applications can be expanded through use of synthetic biology, cell-free protein synthesis and incorporation of unnatural amino acids into proteins. Improved knowledge of protein synthesis should be important for making protein mutants, for protein structural studies and for drug discovery by directed evolution of short proteins containing unnatural amino acids (peptidomimetics). Unnatural amino acids are common and desirable components of drugs because they resist rapid degradation by the body and enable transport to the inside of cells, thereby increasing the activity of the drug and the accessible range of drug targets.
Research projects
Synthetic biology, protein synthesis and drug discovery
SynBio is a creative new field defined as the complex engineering of replicating systems. It encompasses next-generation technology for bioengineering and fresh approaches to global challenges such as drug discovery and biofuels.
Our current projects include:
- Improving ribosomal incorporation of unnatural amino acids for investigating translation mechanism and for applications such as directed evolution of peptidomimetic drugs.
- Development of chromoproteins as reporters and for biosensor diagnostics.
- Understanding and improving transcription termination.
- Improving vaccines via synthetic biology.
- Determining functions of ribosomal RNA modifications towards synthesis of the ribosome and self-replication.
