Biobrick His - CoH2

This composite part consists of T7 promoter (BBa_K3633015), lac operator (BBa_K4165062), pGS-21a RBS (BBa_K4165016), 6x His-tag (BBa_K4165020), CoH2 (BBa_K4165003) and T7 terminator (BBa_K731721).

Usage and Biology

COH protein is a part of the Snitch system, which binds to the His tag for the purification of the COH.

Modeling

Model “peptide (His_Coh2) modeled by TRrosetta model1” Ranked second model from our 4 ones with score 5 out of 6 and values of C Beta deviasion = 0 , clash score = 3.23 , molpro0bitey = 1.59 , Ramachandran favored = 92.31 , Ramachandran outlier = 1.4 , Q Mean_4 = 0.835 , Q Mean_6 = 0.95 


                              Figure 1. The 3D structure of His-COH model visualized by Pymol.

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.
