N3-Gly-Gly-Gly-OH

N3-Gly-Gly-Gly-OH is a oligo-Gly click chemistry reagent containing an azide group. Oligo-Gly also has been used as linker to combine different subunits of dimeric or oligomeric proteins or to create artificial multi-domain proteins. By modification into Gly-Gly-Gly-Ser motifs high solubility can be achieved[1][2][3]. N3-Gly-Gly-Gly-OH 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.
