Flavin photocatalysis
WebA photoproximity labeling approach is described that allows capturing of protein interactomes using brief exposure to visible light. The technology—Light-induced Interactome Tagging (LITag)—involves genetically fusing an engineered flavoprotein to a protein of interest. Excitation of the flavin mononucleotide cofactor leads to covalent ...
