−	Summary: We have adapted the part to be able to assemble transcriptional units with the Golden Gate method and we have done the characterization of this RBS.

−	Documentation:
−	<br>
−	BBa_K2656011 is the RBS [https://parts.igem.org/Part:BBa_B0034 B0034] standardized into the Golden Braid assembly method. 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.
−
−	Characterization of the this part was performed with the transcriptional unit [https://parts.igem.org/Part:BBa_K2656101 BBa_K2656101 ], which was used in a comparative RBS expression experiment with composite parts [https://parts.igem.org/Part:BBa_K2656101 BBa_K2656101] and [https://parts.igem.org/Part:BBa_K2656102 BBa_K2656102].
−	They all were assembled in a Golden Braid alpha1 plasmid using the same promoter, CDS and terminator.
−
−	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.

RBS (Elowitz 1999) -- defines RBS efficiency

RBS based on Elowitz repressilator.

Usage and Biology

IIT Madras 2016's Characterization

Modelling

Global non-modularity towards promoters & protein coding parts and relative strength was estimated for RBSs B0030, B0032, B0034 in our [http://2016.igem.org/Team:IIT-Madras/Model#Modularity_of_RBS_parts modelling]

Experimentation

Biobrick RBSs B0030, B0031, B0032, B0034 were used in our 'Noise in Device' experiment to understand the role of RBS parts in giving rise to noise.

Sequence and Features

Functional Parameters

Note: The Elowitz RBS is the definition of efficiency 1.0.

Team Warsaw 2010's measurement

definition of 100% strength in our measurement.
