The histone variant macroH2A1 contains a carboxyl-terminal ∼30-kDa domain called a macro domain. MacroH2A1 is produced as one of two alternatively spliced forms, macroH2A1.1 and macroH2A1.2. While the macro domain of macroH2A1.1 can interact with NAD(+)-derived small molecules, such as poly(ADP-ribose), macroH2A1.2's macro domain cannot. Here, we show that(More)
Click Chemistry is a set of rapid, selective and robust reactions that give near-quantitative yield of the desired product in aqueous solutions. The Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) that forms 1,4-disubstituted triazoles is a prototypical example of click chemistry that features exquisite selectivity and bioorthogonality-that is,(More)
Bioorthogonal reactions, especially the Cu(I)-catalysed azide-alkyne cycloaddition, have revolutionized our ability to label and manipulate biomolecules under living conditions. The cytotoxicity of Cu(I) ions, however, has hindered the application of this reaction in the internal space of living cells. By systematically surveying a panel of(More)
