A growing body of evidence indicates that phytooxylipins play important roles in plant defense responses. However, many enzymes involved in the biosynthesis of these metabolites are still elusive. We have purified one of these enzymes, the peroxygenase (PXG), from oat microsomes and lipid droplets. It is an integral membrane protein requiring detergent for its solubilization. Proteinase K digestion showed that PXG is probably deeply buried in lipid droplets or microsomes with only about 2 kDa… CONTINUE READING
