Description
Coding sequence for Defensin with His6 and LPXTG-tag regulated by T7-promoter. The function of Defensin is to lyse the pathogenic cell by permeabilizing the plasma membrane.
The inserted LT-sequence contain the gene encoding for His-tag which enables the use of IMAC to purify the combat protein. Furthermore it contains the LXPTG-tag which enables the use of the "match making" enzyme Sortase. The key feature of sortase 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. A new peptide bond is formed. The Linker in the LT-sequence enables proper folding of the protein.
Notes
The LT-sequence was inserted with Overhang PCR.
