Part:BBa_K4472990

Split ribozyme detecting kanamycin and expressing GFP

This composite part is build out of the split ribozyme halfs, guide RNAs complementary to kanamycin resistance mRNA and a GFP reporter. We assembled this part using golden gate assembly and transformed it into E.coli DH5alpha.

In our colony PCRs we were able to confirm that we have assembled the construct correctly as all our PCRs had bands at the expected height of around 1600-1700 bp.

The promoters were too weak to get any signal in our plate reader measurements afterwards. Our model showed that stronger promoters would have had a much stronger effect, see here: https://2022.igem.wiki/uni-hamburg/model
