Pyrrolysine Amber Stop-Codon Suppression: Development and Applications [PDF]

open access: yesChemBioChem, 2017
AbstractThe pyrrolysine tRNA synthetase‐tRNA pair is probably one of the most promiscuous tRNA–synthetase pairs found in nature, capable of genetically encoding a plethora of noncanonical amino acids through stop codon reassignment. Proteins containing reactive handles, post‐translational modification mimics or both can be produced in practical ...

Generation of Amber Suppression Cell Lines Using CRISPR-Cas9

Methods in Molecular Biology, 2023
Genetic code expansion via amber suppression allows cotranslational, site-specific introduction of nonnatural chemical groups into proteins in the living cell. The archaeal pyrrolysine-tRNA/pyrrolysine-tRNA synthetase (PylT/RS) pair from Methanosarcina mazei (Mma) has been established for incorporation of a wide range of noncanonical amino acids (ncAAs)

Site-Specific Labelling of Multidomain Proteins by Amber Codon Suppression [PDF]

open access: yesScientific Reports, 2018
Abstract Amber codon suppression is a powerful tool to site-specifically modify proteins to generate novel biophysical probes. Yet, its application on large and complex multidomain proteins is challenging, leading to difficulties during structural and conformational characterization using spectroscopic methods.

Suppression of an amber mutation by microinjection of suppressor tRNA in C. elegans

Nature, 1982
Informational suppression by nonsense suppressor tRNAs has classically been a powerful tool for study of the mechanism of protein synthesis, to obtain conditional mutants and to demonstrate that a gene encodes a given protein product (for reviews see refs 1–3).
