PolyG Tag (GGGG) for Sortase-mediated Ligation
- Name: PolyG tag
- bp: 12
- Da: 300
- Properties: second sequence for Sortase A
Introduction:
The enzyme Sortase A is able to form a peptide bond between a C-terminal LPXTG motif and a N-terminal poly glycine motif [1][2][3]. The DNA sequence below is coding for four glycines that can be used as the second recognition motif in a Sortase reaction.
