Genetic Encoding of a Photocaged Glutamate for Optical Control …

WebSelenocysteine is the Se-analogue of cysteine. It is rarely encountered outside of living tissue (and is not available commercially) because it is very susceptible to air-oxidation. More common is the oxidized derivative selenocystine, which has an Se-Se bond. [7] Both selenocysteine and selenocystine are white solids. Webthat it requires an activated cysteine. In order to maintain an original cysteine position, a mature approach using ncAA incorporation has been coupled with ACPL10. Evading this major limitation involves synthesizing a photocaged cysteine, and genetically incorporating it into essential cysteine sites by means of amber suppression.
