WebJul 18, 2024 · Here we demonstrate an alternative route, whereby a photocaged selenocysteine (PSc) is incorporated as an unnatural amino acid in response to an amber stop codon, using a mutant Methanosarcina mazei pyrrolysyl-tRNA synthetase, Mm PCC2RS, and its cognate tRNA CUA. Following decaging by UV irradiation, proteins synthesized … Webserine (colored in green) is mostly buried inside the proteins core. Therefore, every small change in this area will probably impact dramatically the tertiary structure of the protein. …
WebIn another example, Chen et al. synthesized two-photonactivatable chemokine CCL5 using photocaged serine through efficient one-pot total chemical synthesis. The chemical groups at serine residues successfully caged the hCCL5 activity, which allowed a spatiotemporally controlled photoactivation of the chemokine activity [ 22 ].
