pT7-CBDcipA-AsPink
A cellulose binding domain (CBD) from Clostridium thermocellum which can be used to purify or attach proteins to cellulose. The part also has a flexible GS-linker with a thrombin site added at the end, clevage with thrombin will add one glycine and one serine to the N-terminal of the fusion protein.
The part has a AsPink (Codon opt. BBa_K1033933) fused to the CBD to ensure easy trackable expression and characterization ([http://www.ncbi.nlm.nih.gov/pmc/articles/PMC5946454 Liljeruhm et al. 2018]) of the CBD. The part has a very strong expression with a T7 promotor (BBa_I719005) as well as a 5'-UTR (BBa_K1758100) region which has been shown to further increase expression in E. coli (BBa_K1758106), ([http://www.ncbi.nlm.nih.gov/pubmed/2676996 Olins et al. 1989]), ([http://www.ncbi.nlm.nih.gov/pubmed/23927491 Takahashi et al. 2013]).
Potential Usages
AsPink can for example be used as a reporter for CBD binding ability, track purification of the CBD or report linker breakage. By including a BamHI site on the linker; the asPink can be switched with another protein.
