AzGGK (TFA)

AzGGK TFA is an unnatural amino acid. AzGGK TFA is site-specifically incorporated into proteins via genetic-code expansion. AzGGK TFA can be used as a site-specific probe for ubiquitylation and SUMOylation. AzGGK TFA is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups^[1].

Click chemistry is used to describe the selective, modular, wide range and high-yield chemical reactions that allow rapid synthesis of new compounds through heteroatom linking (C-X-C). Bertozzi developed click chemistry in a new dimension —Bioorthogonal chemistry. It is defined as a rapid and selective reaction that does not interfere with biological processes under physiological conditions. Common reaction structures of click chemistry, such as Azide, Alkyne, DBCO, BCN, TCO and Tetrazine.
