Design Notes

There is an EcoRI site within the XRP2 terminator making this part RFC10 incompatible. However, we added the BioBrick prefix and suffix so that the other enzymes (NotI, XbaI, SpeI, and PstI) could be used to clone this part into an iGEM plasmid or another plasmid. This part can also be cloned through RFC1000 assembly.

The promoter (BBa_K3629001) is an intronic promoter, however the wild-type sequence contains BsaI, PstI, and SpeI restriction sites in the promoter section before the intron sequence. Therefore, single-nucleotides changes that match the ones in the functional BBa_K2983050 promoter were made to remove theses sites.

The native signal peptide from T. reesei was removed so it would not interfere with the fused Lip2 secretion tag native to Y. lipolytica.

Source

The coding sequence of the CBHI is from Trichoderma reesei, however it has been codon-optimized for optimal activity in Yarrowia lipolytica. The promoter and terminator sequences are from wild-type Y. lipolytica.
