Design
The following gene construct was designed to enable the cloning and expression of the recombinant protein LXYL-p1-2-SpyT-His within a T7 expression system.
Additions to the gene are as follows:
- Gibson forward and reverse overhangs – complementary overhangs outside the protein coding region enables cloning into pET19b via Gibson assembly
- Hexahistidine peptide tag – high affinity to Ni2+ - enables protein purification using Immobilised metal affinity chromatography (IMAC) via a Ni-NTA column.
Additionally, GSG linkers are included between the peptide sequences. This flexible linker was designed to permit individual unhindered protein folding of each component (enzyme and tag).
