RBS

Part:BBa_K4601103

Designed by: Doriane Blaise   Group: iGEM23_Evry-Paris-Saclay   (2023-09-23)


Synthetic RBS designed for NpHR

This part is a synthetic RBS specifically designed for the NpHR halorhodopsin (BBa_K4601003) using the Salis Lab RBS Library Calculator v2.0 [1-3].

Usage and Biology

This RBS was used to drive the expression of NpHR (BBa_K4601003) under the control of the T7 promoter (BBa_K2150031) in the composite part BBa_K4601203.

Using the Salis Lab RBS Library Calculator v2.0 [1-3], the predicted features of this RBS are: 

Translation Initiation Rate (au)	:	10197.93
dG_total (kcal/mol)	:	-4.69
dG_mRNA_rRNA (kcal/mol)	:	-16.64
dG_spacing (kcal/mol)	:	0.0053
dG_stacking (kcal/mol)	:	0
dG_standby (kcal/mol)	:	2.34
dG_start (kcal/mol)	:	-2.76
dG_mRNA (kcal/mol)	:	-12.80
Warnings	:	none

This RBS was selected as predicted to have a Translation Initiation Rate (TIR) of about 10000 au from a library of 108 RBSes (GGGTAATTTKCCAVATVAGSAGGTATTB) for which the estimated TIR range from 2810.71 to 376914.59.
