Design

The following gene construct was designed to enable the recombinant expression of the PAM protein within an E. coli chassis (Figure 3). Gibson forward and reverse overhangs were added the 5’ and 3’ ends for cloning via Gibson Assembly. The SnoopTag sequence was added to the C-terminal to enable the conjugation of the PAM protein to SnoopCatcher containing beta-prefoldin arms of the assemblase scaffold. A hexa-histidine tag was added to the C-terminal end to enable the purification of the protein once expressed by immobilised metal affinity chromatography (IMAC) via a nickel-NTA column. Each gene component was separated by a GSG linker sequences to increase the flexibility between each peptide and prevent steric hindrance of protein folding.
