Figure 2. Competitive enzymatic transglycosylation with the fluoroglycan oxazolines (10 and 17) and the non-fluorinated glycan oxazoline (19).

Figure 2

A mixture of the glycan oxazolines and the acceptor Fmoc-Asn(GlcNAc)-OH (20) in a phosphate buffer was incubated with Endo-A, and the respective transglycosylation products were separated on HPLC and quantified by integration of the peak areas to give the transglycosylation yields.
