This forms 13-hydroperoxylinolenic acid, which is then modified by a dehydrase and undergoes cyclization by allene oxide cyclase to form 12-oxo-phytodienoic acid.
This results in 13-hydroperoxylinolenic acid, which is subsequently altered by a dehydrase and undergoes cyclization by allene oxide cyclase to form 12-oxo-phytodienoic acid.
