WebApr 11, 2024 · A photocaged lysine was inserted at the specific domain of Cas9 responsible for the binding of sgRNA, thus rendering it inactive . The exposure to UV light for 120 s leads to the removal of photocaged lysine, leading to the restoration of Cas9 activity. WebJan 27, 2011 · To confirm that the introduction of the photocaged lysine 1 prevents kinase activity, we coexpressed C-MEK1-ΔN with ERK2 fused to an enhanced green fluorescent protein (EGFP-ERK2)inrestingHEK293ETcells.Immunoblottingrevealedno phosphorylation of the TEY motif in both endogenous ERK1/2 and EGFP-ERK2 (Figures 2 and S2, SI), showing … WebA new photocaged amino acid monomer N ε-(1-(2-nitrophenyl)ethoxycarbonyl)-L-lysine-N-carboxyanhydride (NPE-Lys NCA) was designed. Without the addition of any catalyst/initiator and/or scavenger, lysine-based HBPPs were directly synthesized from the UV phototriggered ring-opening polymerization (ROP) of NPE-Lys NCA by a one-pot method and at ... bl983a70
