CAHS 89226 with a 6X His tag
This biological is the CDS sequence of Cytosolic-abundant heat soluble protein 89226, also called CAHS 89226. It is a kind of Tardigrade intrinsically Disordered Protein (TDP). It is a heat soluble protein found from Tardigrade Hypsibius dujardini in 2017 [1]. Tardigrade, also called water bear, is a kind of tenacious organism. It can survive extreme environment, such as desiccation, freeze and vacuum. The super capacity of Tardigrade partially owes to TDPs. CAHS 89226 has been proven to protect the activity of purified proteins [1]. Here we found that expressing this protein can help bacteria survive the freeze-drying process and then the resultant dry bacteria powder can be stored for a long time at room temperature.

Design
This part is the CDS of CAHS 89226. We obtained the sequence from the research paper in 2017 [1]. Then with the help of a company, we optimized the sequence, so that the part is suitable to work in E. coli and there is no biobrick restriction enzyme cutting site in it. Moreover, we added an 6x His tag at the N-terminal of CAHS 89226, so it can be easily detected by Western Blot and be purified by Ni-chelating affinity chromatography (Fig.1). This year, the part is used in the composite part K3457032
