UbiX with T7 promoter and FLAG tag
Overview
UbiX is a flavin prenyltransferase that normally plays a role in ubiquinone biosynthesis in E. coli. UbiX transfers a prenyl group from dimethylallyl monophosphate (DMAP) to flavin mononucleotide (FMN), thereby creating a cofactor that happens to be essential to the functionality of FDC. Our genetic construct includes the FDC gene, a T7 inducible promoter, a ribosome binding site, and a FLAG-tag peptide sequence for easy and efficient protein purification. We have sequenced our construct and verified that all these components are indeed present. We were able to successfully clone our construct into E. coli and induce expression with isopropyl β-D-1-thiogalactopyranoside (IPTG). A sodium dodecyl sulfate polyacrylamide gel electrophoresis confirmed that our FLAG-tag extraction selectively purified the UbiX enzyme.
