Applications

  1. Biotechnology of the Synthetic Cells and Proteins:
    • Use of engineered organisms and proteins in materials science, medicine, and environmental sustainability.
    • Advances in cell-surface enzyme display and genomic integration for biotechnological innovation.
  2. Biocatalysis with Non-canonical Amino Acids (ncAAs):
    • Development of novel enzymatic systems for industrial and environmental use.
    • Application of orthogonal enzymes in creating specialized chemical transformations.
  3. Classical and Modern Protein Chemistry:
    • Fusion of classical peptide synthesis with advanced protein design.
    • Studies in folding, stability, and novel chemistries within engineered proteins.
  4. Bioorthogonal Conjugations & Click Chemistry:
    • Labeling, tracking, and modifying biomolecules in research, diagnostics, and therapeutic applications.
    • Study biological processes in real time without causing unwanted side effects.
  5. Protein and Cellular Biophysics with Site-specific Labeling:
    • Spectroscopic probes: Incorporated ncAAs can carry unique handles (e.g., nitrile groups) for specialized spectroscopic techniques such as IR, NMR, or fluorescence measurements.
    • Mapping local environments: ncAAs sensitive to electric fields or hydrogen bonds provide direct insight into microenvironments within proteins and membranes.
Cold-wash lipase: Our group has engineered a thermostable lipase by replacing methionine with norleucine, thereby improving the catalytic activation of the enzyme at low temperatures. The residue-specific insertion of norleucine also prevents unwanted oxidation that impairs activity, thereby extending enzyme function under harsh conditions, which ultimately drives global industrial and commercial applications in protein engineering (see patent: EP2431461 - Lipase congeners with improved substrate access).
