Design Notes

Because of complexity of TPA in part due to the multiple disulfide bridges the expression of active TPA in bacterial cultures is diffucult and limited. Previous papers [2], have indicated that active TPA can be produced in yeast cultures at reasonably high concentration. The amino acid sequence of TPA from Uniprot, was codon optimized for yeast, and two silent mutations were made to make the part RFC[1000] compatible. Homology for the p4XX yeast plasmid series was added for transformation. The alpha mating factor tag was added for the intracellular production of the protein. A flexible linker made up of the GGGGS motif was used to hopefully improve activity of the binded protein [3].
