CYP3A4-pGAL1/10-POR detox module against a wide array of contaminants

In our system, the CYP3A4-pGAL1/10-POR composite part combines the CYP3A4 enzyme and cytochrome P450 oxidoreductase (POR) to form a highly efficient detoxification unit. The pGAL1/10 bidirectional promoter drives the expression of both CYP3A4 and POR simultaneously but in opposite directions. CYP3A4, a key phase I enzyme, is responsible for oxidizing around 50% of all clinically used drugs and environmental toxins. POR provides the electrons required for these oxidation reactions by transferring electrons from NADPH to CYP3A4, ensuring efficient metabolism of harmful xenobiotics and pharmaceuticals.

This composite part was cloned using the method of USER-cloning into YCp-H. YCp-H is a centromeric plasmid used in yeast that includes a HIS3 marker, allowing for selection in histidine auxotrophic yeast strains. Like other CEN plasmids, YCp-H contains a CEN sequence, ensuring that the plasmid replicates and segregates similarly to yeast chromosomes. This results in a low copy number (typically one to two copies per cell), providing stable maintenance of the plasmid.
