Design Notes
The RiAFP is expressed when around 300 mM NaCl added. This part was designed by adding a 6xHis tag for affinity purification to the anti freeze protein from Raghium inquisitor. This part was codon optimized for its expression in E.coli.
Source
The Raghium inquisitor Anti Freeze Protein (RiAFP) is a 137 AA protein that prevents the growth of ice crystals by adsorption to their surface. The proU promoter is from E.coli and works activating transcription when the bacterium is osmotically stressed. (Kristiansen E, 2011)
