Profiling enzyme activities in vivo using click chemistry methods.
Methods for profiling the activity of enzymes in vivo are needed to understand the role that these proteins and their endogenous regulators play in physiological and pathological processes. Recently, we introduced a tag-free strategy for activity-based protein profiling (ABPP) that utilizes the copper(I)-catalyzed azide-alkyne cycloaddition reaction ("click chemistry") to analyze the functional...
متن کاملMonitoring Dynamic Glycosylation in Vivo Using Supersensitive Click Chemistry
To monitor the kinetics of biological processes that take place within the minute time scale, simple and fast analytical methods are required. In this article, we present our discovery of an azide with an internal Cu(I)-chelating motif that enabled the development of the fastest protocol for Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) to date, and its application toward following the dyn...
متن کاملImaging Cell Surface Glycosylation in Vivo Using “Double Click” Chemistry
Dynamic alterations in cell surface glycosylation occur in numerous biological processes that involve cell-cell communication and cell migration. We report here imaging of cell surface glycosylation in live mice using double click chemistry. Cell surface glycans were metabolically labeled using peracetylated azido-labeled N-acetylgalactosamine and then reacted, in the first click reaction, with...
متن کاملIn vivo targeting through click chemistry.
Targeting small molecules to diseased tissues as therapy or diagnosis is a significant challenge in drug delivery. Drug-eluting devices implanted during invasive surgery allow the controlled presentation of drugs at the disease site, but cannot be modified once the surgery is complete. We demonstrate that bioorthogonal click chemistry can be used to target circulating small molecules to hydroge...
متن کاملActivity-based protein profiling: from enzyme chemistry to proteomic chemistry.
Genome sequencing projects have provided researchers with a complete inventory of the predicted proteins produced by eukaryotic and prokaryotic organisms. Assignment of functions to these proteins represents one of the principal challenges for the field of proteomics. Activity-based protein profiling (ABPP) has emerged as a powerful chemical proteomic strategy to characterize enzyme function di...
