Abstract Proteins are the workhorses of the cell, playing crucial roles in virtually every biological process. The revolutionary ability to visualize and monitor proteins in living systems, which is largely the result of the development of green fluorescence protein (GFP) and its derivatives, has dramatically expanded our understanding of protein dynamics and function. Still, GFPs are ill suited in many circumstances; one major drawback is their relatively large size, which can significantly perturb the functions of the native proteins to which they are fused. To bridge this gap, scientists working at the chemistry-biology interface have developed methods to install bioorthogonal functional groups into proteins in living cells. The bioorthogonal group is, by definition, a non-native and n......
