Part:BBa_K4165167
His - DocS
This composite part consists of T7 promoter (BBa_K3633015), lac operator (BBa_K4165062), RBS 4 (BBa_K4165264), 6x His-tag (BBa_K4165020), DocS (BBa_K3396000) and T7 terminator (BBa_K731721).

Usage and Biology
DOCs protein is a part of the Snitch system, which binds to the His tag for the purification of the Docs.

Modeling
Model “peptide (His_DocS) modeled by TRrosetta model1” Ranked Third model from our 4 ones with score 5 out of 6 and values of C Beta deviasion = 0 , clash score = 0 , molprobitey = 0.77 , Ramachandran favored = 96 , Ramachandran outlier = 0 , Q Mean_4 = -0.29 , Q Mean_6 = -0.27

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 2. 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.
