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. It also includes the BioBrick equivalent scar in the 3' extreme, so the insertion of this supplementary bases ensure correct spacing for the ribosome to bind to.
This RBS is part of our complete Printeria RBS Basic Part Collection
|Part||BioBrick||Description||Strength (Relative to BBa_K2656009)|
|BBa_K2656008||BBa_J61100||Very weak RBS||0.042|
|BBa_K2656012||BBa_J61101||Very weak RBS||0.032|
Using the Golden Gate assembly protocol , it can be combined with other Golden Braid basic parts, such as the ones from our Valencia UPV IGEM 2018 Printeria Collection, to assemble transcriptional units in a single BsaI one-pot reaction.
Characterization of 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 Part Collection
- CDS BBa_K2656013: the BBa_I746916 sfGFP sequence in its Golden Braid standardized version from our Part Collection
- Terminator BBa_K2656026: the B0015 transcriptional terminator in its Golden Braid compatible version from our Part Collection

|Translation rate p||p = 0.04089 min-1|
|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. It has been defined as the quotient between the values of the protein in equilibrium of the results of the simulation of one RBS and the reference RBS. Likewise, a ratio between p parameters of the different RBS parts and p parameter of the reference RBS has been calculated.
