Design Notes

Our goal was to have production of AtAAE3 under tight inductive control, so a galactose-inducible, glucose-repressible pGAL1 promoter was utilized. An ATUM-default yeast Kozak consensus sequence (aAaAaAATGTCt) was utilized with minor modifications. Specifically, we deleted the last 5 nucleotides since our AtAAE3 gene already contains a start codon. Note that we incorporated the Kozak into our gene itself (Part: BBa_M50433). The pGAL1 promoter was also We also used ATUM’s default pGAL1 promoter (iGEM Part: BBa_J63006). Our coding sequence also had a 6X HIS tag inserted at the C-terminus. Moreover, the terminator utilized was also a default ATUM terminator for S. cerevisiae (iGEM Part: K1462070). The plasmid vector from ATUM utilized was pD1201. Overall, our basic parts were optimized for yeast, since previous literature conducted similar oxalate experiments in yeast. An E. coli glycerol stock (Barcode: 0133024479) for culture in LB + kanamycin media and a yeast glycerol stock for culture in 2% raffinose (Barcode: 0133011812) were made by mixing cultures in 1:1 ratio with 50% glycerol.


The coding sequence comes from the analogous oxalyl-CoA synthetase of the species Arabidopsis thaliana. The sequence of for the AtAAE3 gene (iGEM Part: BBa_M50433) was derived from the European Nucleotide Archive via UniProtKB (UniProtKB Entry: Q9SMT7). The actual sequence was submitted by Salanoubat et al. We then codon-optimized this sequence for S. cerevisiae, the organism we engineered, and added a 6X HIS tag to the end of the coding sequence for Western Blotting ourselves.
