Cytosolic-abundant heat soluble protein "CAHS " (promoter, RBS, RFP, lacI and double terminator)

SUMMARY

This part contains the coding region of the Hypsibius dujardini (Water bear) (Macrobiotus dujardini) CAHS gene. Cytosolic abundant heat soluble proteins acting as a molecular shield in water-deficient condition. Tardigrade-specific intrinsically disordered proteins (TDPs) are essential for desiccation tolerance by forming non-crystalline amorphous solids upon desiccation, and this vitrified state mirrors their protective capabilities.
CAHS is a cytoplasmic-abundant protein which can strength the bacteria stress tolerance under the conditions such as dehydration. So taking biosafety into account, we add a constant promoter BBa_J23100 into the CAHS circuit to express Lac I BBa_S0100 in order to inhabit the initiation of the Lac O BBa_R0011 promoter which can only be activated and then expressing CAHS and mRFP BBa_J04650 after IPTG is added.
The separate fragment of CAHS is 714bp, and the whole circuit is 2934bp.The plasmid skeleton is pSB1C3.

Identification

When we are building this circuit, we are doing the nucleic acid gel electrophoresis experiment to verify. After the circuit is built, we send the plasmid to sequence, and get the correct sequencing. After new molecular cloning experiments, we do Enzyme-Cut identification to certify the plasmid is correct. We use the EcoR I and Pst I to cut the plasmid, then we getting two fragments - one is 2932bp, and the other is 2029bp.
