Spytag and spycatcher
Web9 May 2014 · SpyTag is a peptide that spontaneously forms an amide bond with its protein partner SpyCatcher. SpyTag was fused at the N terminus of β-lactamase and SpyCatcher at the C terminus so that the partners could react to lock together the termini of the enzyme. The wild-type enzyme aggregates above 37 °C, with irreversible loss of activity.
