uridine diphosphate glycosyltransferases UGT85K4 and UGT85K5 are co-expressed with CYP79D1 and CYP71E7 paralogs, which catalyze earlier steps in cyanogenic glucoside synthesis, in the cortex, xylem and phloem parenchyma, and in specific cells in the endodermis of the petiole of the first unfolded leaf

in nearly unfolded leaves, the CYP71E7 paralogs are preferentially expressed in specific cells in the endodermis and in most cells in the first cortex cell layer. In fully unfolded leaves, the expression is pronounced in the cortex cell layer just beside the epidermis and in specific cells in the vascular tissue cortex cells
parenchyma cells of the first unfolded leaf.

CYP71E7 is the oxime-metabolizing cytochrome P450 in the biosynthesis of lotaustralin and linamarin. Expression of CYP71E7 in yeast affords microsomes converting 2-methylpropanal oxime and 2-methylbutanal oxime to the corresponding cyanohydrins, which dissociate into acetone and 2-butanone, respectively, and hydrogen cyanide
