Coding sequence for Sortase A with His-tag
Usage
Sortase A is a bacterial enzyme with the ability to break and form new peptide bonds. The key feature of the enzyme is the specific conjugation reaction it carries out, where the enzyme recognizes a specific amino acid sequence, a so called sorting motif (LPXTG motif in the case of S.aureus) and conjugate this sequence with another unit carrying an oligo glycine motif where a new peptide bond is formed [1],[2].
Biology & BioBrick Design
This Biobrick is a truncated version of the enzyme where the transmembrane domain (amino acids 1-59) is not included in the coding sequence to increase solubility [2]. The BioBrick has also been fused with the Protein G B1 Domain (GB1) acting as a solubility tag and a His-tag to enabling purification through IMAC [2].
