Part:BBa_K4601100

Synthetic RBS designed for CatCh

This part is a synthetic RBS specifically designed for the CatCh channelrhodopsin (BBa_K4601000) using the Salis Lab RBS Library Calculator v2.0 [1-3].

Usage and Biology

This RBS was used to drive the expression of CatCh (BBa_K4601000) under the control of the T7 promoter (BBa_K2150031) in the composite part BBa_K4601200.

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

Translation Initiation Rate (au)	:	9603.17
dG_total (kcal/mol)	:	-4.56
dG_mRNA_rRNA (kcal/mol)	:	-10.65
dG_spacing (kcal/mol)	:	0
dG_stacking (kcal/mol)	:	0
dG_standby (kcal/mol)	:	1.09
dG_start (kcal/mol)	:	-2.76
dG_mRNA (kcal/mol)	:	-8.24
Warnings	:	none

This RBS was selected as predicted to have a Translation Initiation Rate (TIR) of about 10000 au from a library of 128 RBSes (GGGTAGWGTATTCWMMTWAGGASGTAARTT) for which the estimated TIR range from 1424.62 to 1054132.03.
