Glycoconjugates play critical roles in regulating cellular and organismal functions.
Consequently, defining the relative levels of these glycoconjugates under varied
physiological conditions is important. Thus identifying and understanding the regulation of
the enzymes that process these glycoconjugates are essential steps in understanding the
role of this “glycocode” in development and disease. Activity‐based affinity reagents are
useful tools for probing these enzymes and should facilitate the unraveling of proteomes …
