The suppression of amber stop codons with non-canonical amino acids (ncAAs) is used for the site-specific introduction of many unusual functions into proteins. Specific orthogonal aminoacyl-tRNA synthetase (o-aaRS)/amber suppressor tRNA(CUA) pairs (o-pairs) for the incorporation of ncAAs in S. cerevisiae were previously selected from an E. https://foldlyers.shop/product-category/novelty-products/
