Part:BBa_K2306007:Design
Secretory-abundant heat soluble protein 68234 "SAHS 68234" (T7 promoter, RBS and double terminator)
This composite BioBrick features the basic part BBa_k2306002 that codes for the production of the tardigrade intrinsically disordered protein (TDP) "SAHS 68234". This is one of the several heat soluble proteins found in the tardigrades capable of protecting other fragile biological parts upon desiccation by generating a crystal matrix. Therefore, this tardigrade protein can be combined with other perishable biological material (e.g. proteins) to increase its stability after dehydration or even enable the possibility of stabilizing material with just a previous drying step. The sequence encoding for the gene is preceded by a T7 promoter BBa_I712074 and an RBS BBa_K2306014, which allows inducible overexpression of the protein with IPTG; and followed by a double terminator consisting of a rrnB T1 terminator and T7Te terminator BBa_B0015. This was the part employed in TU Delft's project for the expression and production of SAHS 68234. More information about our project can be found on our [http://2017.igem.org/Team:TUDelft/Results#TDP results page].

Design Notes
A T7 promoter and a strong RBS were chosen to the end of maximizing the production of the protein and therefore enable the subsequent characterization experiments
