FIGURE 4.

Schematic drawing of the biosynthetic pathway for linamarin and lotaustralin in three legume species. Members of the CYP79 family convert valine and isoleucine into their corresponding oximes. The oxime metabolizing enzyme is a CYP83 in P. lunatus, and a CYP736 in L. japonicus and T. repens. The hydroxynitriles are glucosylated by members of the UGT85 family. The stereochemistry of the oximes produced by P. lunatus is presently unknown, the forms shown are the Z‐isomer. Colored boxes indicate that genes belong to the same gene family
