Biobrick GST - CoH2 - Linker - WWW

This composite part consists of T7 promoter (BBa_K3633015), lac operator (BBa_K4165062), RBS 4 (BBa_K4165264), GST (BBa_K4165070), CoH2 (BBa_K4165003), GGGGSx3 (BBa_K4165068), WWW (BBa_K4165007), and T7 terminator (BBa_K731721).

Usage and Biology

The protac in our snitch system, it is responsible for connecting the target protein (tau) to the tTrim21 which binds to E2 conjugating enzymes and put tau and ubiquitin in proximity to each other resulting in ubiquitination of the tau at lysine residue, after ubiquitination the tau will be degraded by 26S proteosome.

Modeling

From 3 models out of 16 Models modeled in 4 software, 1 Model ranked best according to its Q_Mean values 4 and 6. The best Model has values of : score 5 out of 6 , C-Beta deviation = 1 , clash score = 3.08 , molprobitey = 1.35 , Ramachandran favored = 96.31, Ramachandran outlier = 0.79 , Q Mean_4 = -0.01 , Q_Mean_6 = -0.29.

Mathematical modeling

Transcription rate and translation rate under T7 promotor

the mathematical modeling was based on our code for the calculation of transcription and translation (you can find it in the code section) beside with the estimated results from the wet lab. 

                 Figure 1. this figure shows the results from the transcription and translation code showing the 
                     variation of mRNA and protein concentrations with time compared with the wet lab results.
