Application

The in-vivo incorporation of clickable unnatural amino acids such as 4-Azido-L-phenylalanine with unique reactivity at a defined postition is used for functionalization of proteins. The azide functionalities in the protein can then be modified with almost any alkyne bearing molecule by Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC). Copper-free alternatives with strained internal alkynes are also available (SPAAC). Some examples enabled with this technique are protein PEGylation, masking with sugars, and the attachment to antibodies.

Paramyxovirus membrane fusion requires an attachment protein that binds to a host cell receptor and a fusion protein that merges the viral and host membranes. For Nipah virus (NiV), the G attachment protein binds ephrinB2/B3 receptors and activates F-mediated fusion.
