WebOct 1, 2024 · For this purpose, a photocaged ß-fluoro-tyrosine (FnBY, Figure 2 e) derivative was designed that, upon UV-irradiation, generates a quinone methide. Proof-of-principle experiments showed site-specific incorporation of FnBY into GST and UV-induced Michael addition with natural nucleophilic amino acids to covalently crosslink the GST homodimer … 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.
