Biosynthesis/Oximes/CYP79A2

This BioBrick BBa_K527000 encode the plant enzyme Cytochrome P450 CYP79A2. Cytochromes P450 are defined as heme-thiolate proteins featuring a particular spectral signature at 450 nm, thus the name. Despite the label as cytochromes, these proteins are not involved in electron transfers, but act as monooxygenases in a wide range of reactions such as epoxidation, N-dealkylation, O-dealkylation, S-oxidation and hydroxylation.

CYP79A2 is an N-hydroxylase converting L-phenylalanine into phenylacetaldoxime, the precursor of a cyanogenic glycoside. Oximes as the phenylacetaldoxime is generally toxic to fungi and is frequently used as a chemical fungicide. They function by inhibiting mitochondrial oxidases and thereby promote lipid peroxidation and the production of toxic reactive oxygen species.
