Part:BBa_K2333415
UNS J23100 mScarlet-I pdt B
This part is contained in a suite of protein degradation tagged mScarlet reporters under the control of the strong constitutive promoter BBa_J23100. These parts, in combination with inducible mf-Lon protease constructs, allowed William and Mary 2017 to characterize the degradation properties of each protein degradation tag (pdt) on a plasmid-based system. William and Mary 2017 successfully demonstrated distinct levels of protein degradation by each of the 6 pdt’s, and mScarlet reporters have been codon-optimized for E. coli and feature a double stop codon for enhanced efficiency. This specific part contains pdt B, one of the 6 pdt's, which was used to generate a distinct effect on the speed of a tagged protein’s expression.
Usage and Biology
This part contains mScarlet-I with pdt-B under the control of the constitutive promoter BBa_J23100. Protein degradation tag B is the second strongest of the 6 protein degradation tags that William and Mary 2017 characterized, and is associated with the E. Coli orthogonal protease mf-Lon (BBa_K2333011). This part also contains a double stop codon and BBa_B0015 (double terminator) in the William and Mary iGEM Universal Nucleotide Sequences (UNS) format. This enables easy cloning with Gibson Assembly, as UNS primers are designed for easy PCRs and high yield Gibson Assembly. Using this part in combination with inducible mf-Lon protease constructs, William and Mary 2017 was able to characterize the degradation properties of protein degradation tag B on a plasmid-based system. This is a part of the first experimentally-demonstrated system that allows future iGEM teams to access modular, predictive control over the temporal dynamics of their circuits by swapping parts at the genetic sequence level.
Characterization
W&M 2017 characterized this tagless construct in combination with inducible mf-Lon protease constructs as a control for their strength of degradation measurements. The graph below shows degradation strength data along with the data from the other tags in this series (BBa_K2333413-BBa_K2333419).
