Biobrick His - CoH2
This composite part consists of T7 promoter (BBa_K3633015), lac operator (BBa_K4165062), RBS 4 (BBa_K4165264), 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 the second model from our 4 ones with a score 5 out of 6 and values of:
cbeta_deviations | clashscore | molprobity | ramachandran_favored | ramachandran_outliers | Qmean_4 | Qmean_6 |
---|---|---|---|---|---|---|
0 | 3.23 | 1.59 | 92.31 | 1.4 | 0.835 | 0.95 |

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.
Wet-Lab Results
A comparison between the Dry-Lab model and the Wet-Lab results of His-CoH2 part using sonicator
Figure 3. This graph shows the correlation between the mathematical model of the dry lab and the wet lab results of His COH using sonicator.
Figure 4. This graph shows that the mathematical model of the dry lab and the wet lab results of His COH using chemical lysis don't correlate with each other as there is a significant difference between the results.
