BBa_K2656011 is the original RBS [https://parts.igem.org/Part:BBa_B0034 B0034] standardized into the Golden Braid assembly method. Thus, it is medium ribosome binding site 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 CDS expression when assembled into a TU.

BBa_K2656011 is the original RBS B0034 standardized into the Golden Braid assembly method. Thus, it is medium ribosome binding site 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 CDS expression when assembled into a TU.

This RBS is part of our complete Printeria RBS Basic Part Collection

Part BioBrick Description Strength (Relative to BBa_K2656009)
BBa_K2656009 BBa_B0030 Strong RBS 1
BBa_K2656011 BBa_B0034 Medium RBS 0.38
BBa_K2656010 BBa_B0032 Weak RBS 0.047
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 GB adapted 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 this part was performed with the transcriptional unit BBa_K2656101 , which was used in a comparative RBS expression experiment with composite parts BBa_K2656101 and BBa_K2656102. 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_K2656009 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 [http://2018.igem.org/Team:Valencia_UPV/Modeling#optimization optimization values] based on each RBS tested.

Parameter Value
Translation rate p p = 0.082 min-1
Dilution rate μ μ = 0.01631 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 another reference RBS. Likewise, a ratio between p parameters of the different RBS parts and p parameter of the reference RBS has been calculated.
