 The last enzyme in dhurrin synthesis, UGT85B1, is a soluble enzyme which exchanges glucose from UDP-glucose to the aglycone of dhurrin and forms the glycosidic bond.Addition of both CYP79A1 and CYP71E1 into the genomes of "Arabidopsis thaliana" and "Nicotiana tabacum" has been shown to be sufficient for Dhurrin production to occur.Both of these enzymes are sufficient and necessary for Dhurrin production, as removal of the CYP79A1 gene from the "Sorghum bicolor" genome results in plants lacking dhurrin content.
