Introduction

CBDcipA-GS+Thrombin linker
A cellulose binding domain (CBDcipA) from Clostridium thermocellum Cellulose scaffolding protein (CipA) which can be used to purify or attach proteins to cellulose, this part has a sfGFP fused to the CBDcipA. The part also has a flexible GS-linker (-GGGGSGGGGS-) with a thrombin site (-LVPRGS-, thrombin RS) added at the end, clevage with thrombin will add one glycine and one serine to the N-terminal of the C-terminal fusion protein of the CBDcipA.

Assembly techinique used

Also added a BamHI recognition sequence (BamHI RS) to enable changeable fusion protein to the CBDcipA. BamHI was chosen because its RS codes for one glycine and one serine, fitting it to the end of the thrombin site, BamHI can also be used on dam/dcm methylated DNA, which is crucial to this part.

For our method "pink-white screening" utilizing a chromoprotein to assemble this part with fusion proteins please see: BBa_K3182100.
The expressional system used to characterize this part was a combination of: BBa_I719005 BBa_K1758100.
