Terminator.png

ECK120015170 terminator

  • This is a natural terminator from E. coli.

Secondary Structure

Team: BNDS_China 2022 data and characterization method from literature review

Characterization data

The ECK120015170 terminator is a very strong terminator. A strong terminator can enhance the protein expression which may help other iGEM teams increase protein expression efficiency in their projects. The strength of the ECK120015170 can be reflected by the ratio of the expression level of two fluorescent proteins: GFP and RFP.

The source organism is E.coli. The genomic sequence is ACAATTTTCGAAAAAACCCGCTTCGGCGGGTTTTTTTATAGCTAAAA

This terminator is contained in a constructed plasmid. The arabinose-induced GFP expression plasmid—pGR-ECK120015170—which contains araC, araBAD promoter, RBS, GFP, ECK120015170 terminator and RFP was used to characterize terminator ECK120015170. The GFP gene is set upstream and RFP is placed downstream of the ECK120015170 terminator.

Quantitative Characterization

The average GFP intensity under the treatment of arabinose is 15714.00, and the average RFP intensity under the treatment of arabinose is 141.53. According to this method, the terminator strength (Ts) of ECK120015170 is 99.59 which corresponds to a high terminator strength.
