Part:BBa_K2656008
Very Weak Ribosome Binding Site J61100
Part BBa_K2656008 is the original RBS BBa_J61100 standardized into the Golden Braid assembly method. Thus, it is a very weak RBS compatible both with the BioBrick and Golden Gate grammar.
Using the [http://2018.igem.org/Team:Valencia_UPV/Protocols Golden Gate assembly protocol], it can be combined with other Golden Braid basic parts, such as the ones from our [http://2018.igem.org/Team:Valencia_UPV/Part_Collection Valencia UPV IGEM 2018 Printeria Collection], to assemble transcriptional units in a single one-pot reaction.
Characterization of the this part was performed with the transcriptional unit BBa_K2656100, which was used in a comparative RBS expression experiment with composite parts BBa_K2656104 and BBa_K2656101. They all were assembled in a Golden Braid alpha1 plasmid using the same promoter, CDS and terminator:
- Promoter BBa_K2656004: the J23106 promoter in its Golden Braid compatible version from our [http://2018.igem.org/Team:Valencia_UPV/Part_Collection Part Collection]
- CDS BBa_K2656013: the BBa_I746916 sfGFP sequence in its Golden Braid standardized version from our [http://2018.igem.org/Team:Valencia_UPV/Part_Collection Part Collection]
- Terminator BBa_K2656026: the B0015 transcriptional terminator in its Golden Braid compatible version from our [http://2018.igem.org/Team:Valencia_UPV/Part_Collection Part Collection]
By using this [http://2018.igem.org/Team:Valencia_UPV/Experiments#exp_protocol experimental protocol], we have obtained the parameters to valide our [http://2018.igem.org/Team:Valencia_UPV/Modeling#models constitutive model]and rationale choose its optimized values based on each RBS.

Dilution rate μ | μ = 0.01288 min-1 |
We have also calculated the relative force between the different RBS, taking BBa_K2656009 strong RBS as a reference. Likewise, a ratio between p parameters of the different RBS parts and p parameter of the reference RBS has been calculated.
