Genetic Code Expansion: Amber Suppression Race

Interactive 3D model of nonsense-suppression genetic code expansion: watch ribosomes race an orthogonal ncAA-tRNA against release factor 1 (RF1) at an engineered amber (UAG) stop codon, tune ncAA concentration, orthogonal tRNA expression and RF1 activity, and read live suppression efficiency and full-length protein yield.

Watch ribosomes translate a transcript with an engineered amber (UAG) stop codon recoded to carry a non-canonical amino acid. At that codon, every ribosome races an orthogonal ncAA-charged suppressor tRNA against release factor 1 (RF1) — a real kinetic-partitioning competition used to biofabricate site-specifically labelled therapeutic proteins such as antibody–drug conjugates. Tune ncAA concentration, orthogonal tRNA/synthetase expression and RF1 activity (or switch to an RF1-attenuated chassis strain) and watch live suppression efficiency and full-length protein yield respond.

Watch ribosomes race an orthogonal ncAA-charged suppressor tRNA against release factor 1 at an engineered amber (UAG) codon, the real kinetic competition synthetic biologists use to biofabricate site-specifically labelled therapeutic proteins.
