Design note

The TEV cutting site used is the classic site already cleaved, composed of 5 amino acids: ENLYFQ.

The construction has a RiboJ insulator (BBa_ K1679038) and a BCD2 (BBa_ J364100).

RiboJ : After transcription, RiboJ becomes a section of functional RNA which comprises the sTRSV- ribozyme and an additional 23-nt hairpin immediately downstream to help expose the RBS. STRSV can cleaves the mRNA autocatalytically at a defined residue, which had the effect of cleaving extraneous RNA leaders that arose from transcription from promoters with different start sites.[6] Attributed to the biochemical function mentioned above, RiboJ has insulating capability. We use it to buffer synthetic circuits from genetic context.

BCD2 : This is one of the bicistronic design elements designed by Mutalik et al. in the 2013 Nature publication [7] (citation below). Specifically, this is bicistronic design element number two (or BCD2, for short).

This sequence was synthesized by IDT DNA for iGEM Headquarters.

This share is strongly expressed.
