UNS J23100 sfGFP pdt D
This part is designed to facilitate easy measurement of the strength of protein degradation tag (pdt) D by measuring time to steady-state fluorescence values of sfGFP under the control of the strong constitutive promoter J23100. William and Mary iGEM 2017 used pdts as a method to control gene expression speed.This part was utilized to characterize the degradation properties of pdt D and confirm the fact that different pdts have different degradation strengths. See [http://2017.igem.org/Team:William_and_Mary/Results William and Mary's 2017 project] for more details. This part is one of a series of sfGFP reporter pdt parts. Series range is from BBa_K2333407 to BBa_K2333412
Usage and Biology
Protein degradation tag D (BBa_K2333004) is of medium strength among the 6 protein degradation tags that William and Mary 2017 characterized, and is associated with the E. Coli orthogonal protease mf-Lon (BBa_K2333011). Therefore this part has a medium degradation rate among the 6 protein degradation tags and it is the third slowest to reach the steady-state fluorescence value. This part contains J23100 constitutive promoter, BBa_B0034 (RBS),pdt D, a double stop codon and BBa_B0015 (double terminator) in the William and Mary iGEM Universal Nucleotide Sequences (UNS) format. See Torella, et. al (2013). In order to demonstrate that protein degradation tags operated similarily regardless of the tagged protein, sfGFP reporters that were analogous to the mScarlet-I parts (BBa_K2333413 to BBa_K2333419) were built and characterized. This demonstrates that the protein degradation tags are modular and that they have differential strengths even when they are tagged on different proteins.
