Abstract

Abstract: Structural proteomics refers to large‐scale mapping of protein structures in order to understand the relationship between protein sequence, structure, and function. Chemical labeling, in combination with mass‐spectrometry (MS) analysis, have emerged as powerful tools to enable a broad range of biological applications in structural proteomics. The key to success is a biocompatible reagent that modifies a protein without affecting its high‐order structure. Fluorine, well‐known to exert profound effects on the physical and chemical properties of reagents, should have an impact on structural proteomics. In this Minireview, we describe several fluorine‐containing reagents that can be applied in structural proteomics. We organize their applications around four MS‐based techniques: a) affinity labeling, b) activity‐based protein profiling (ABPP), c) protein footprinting, and d) protein cross‐linking. Our aim is to provide an overview of the research, development, and application of fluorine‐containing reagents in protein structural studies. Abstract : The combination of mass spectrometry and chemical labeling has become a powerful approach in structural proteomics. Fluorine substitution enables the development of a wide range of biocompatible reagents for interrogating the high‐order structure and functions of proteins. This Minireview focuses on the application of fluorine‐containing reagents in structural proteomics.
