Design

The following gene construct was designed to enable the cloning and expression of the recombinant proteins PAM-SnoopTag and TycA-SpyTag within a T7 expression system.

Additions to the gene are as follows:

  • Gibson forward and reverse overhangs – complementary overhangs outside the protein coding region enable cloning into pET-19b plasmid 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 system).
