GFP-SpyTag (constitutive)

We designed our GFP-SpyTag Biobrick to test bacterial cell adhesion through fluorescence microscopy. This part produces the GFP-SpyTag fusion protein constitutively, which can then be cell extracted and purified to use in combination with cells expressing our SpyCatcher construct variants. SpyTag (13 amino acids) and SpyCatcher (138 amino acids, 15 kDa) are protein binding partners that form spontaneous irreversible isopeptide bonds between an aspartate residue in SpyTag and a lysine residue in SpyCatcher. These binding partners originate from CnaB2 (immunoglobulin-llike collagen adhesin domain) of the FbaB protein, found in the invasive strains of S. pyogenes.
