Translation enhancing 5-UTR + sfGFP under control of T7 promoter

sfGFP (BBa_I746916) under control of the T7 promoter (BBa_I719005). The part includes a translation enhancing sequence, 5'-UTR, which improves the binding of the mRNA to the ribosome ([http://www.ncbi.nlm.nih.gov/pubmed/2676996 Olins et al. 1989]) and is especially helpful in in vitro cell free protein synthesis. The 5'-UTR sequence contains a spacer of 10 adenine bases which has been shown to further enhance translation efficiency ([http://www.ncbi.nlm.nih.gov/pubmed/23927491 Takahashi et al. 2013]). The part also contains a double terminator made of B0010 and B0012.

This part is based on BBa_I746909 but contains an optimized untranslated region (UTR), which improves the sfGFP expression in vivo as well as in vitro.

In vivo characterization of sfGFP with and withour a translation enhancing 5'-UTR. Relative fluorescence units were normalized on OD600. Error bars represent standard deviation of triplicates.


As can be seen in the picture, the difference was observable with the naked eye as well.
