Photocaged serine
Webencoding of a photocaged serine in the TET1 active site enables its translation in an inactive state, followed by its light activation and monitoring of global 5hmC formation in a virtually 5hmC-free genomic background. Coexpression of TET1 with the five human core family MBDs leads to differential modulation of oxidation with MBD1 acting as a WebJun 6, 2024 · Photocaged DMNB-Sec (Figure 1b) was synthesized as previously reported. 22 Incorporation of DMNB-Sec into GFP in mammalian cells was achieved using the E. coli …

WebJul 18, 2024 · Selenocysteine (Sec) is a naturally occurring amino acid that is also referred to as the 21st amino acid. Site-specific incorporation of Sec into proteins is attractive, … In another example, Chen et al. synthesized two-photon-activatable 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].
