Design Notes

The INPN will be embedded in the outer cell membrane of E. coli. This can in turn be fused to a linker to present a protein on the outside of the bacterial cell.

The part uses the two front-end sub-repeats of the middle repeat domain of INP (AxYGSxxxxxNHSxLI). The pelB signal peptide is fused to the 5’ end of the INP-N domain, as its expression promotes the secretion of the protein via the Sec pathway whilst avoiding hydrolysis by cytoplasmic proteases that might lower the quantity of proteins on the cell’s surface (Mergulhao et al., 2005).

Source

This ice nucleation protein is derived from Pseudomonas syringae. The codon optimized sequence for E. coli (BL21 DE3) has been derived from the research performed by Zhu et al. (2022).
