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.
