A pathway for biosynthesis of divinyl ether fatty acids in green leaves.

abstract：:Potato tuber lipoxygenase (ptLOX) has been shown to catalyze the aerobic formation of at least four major oxygenated derivatives of DHA. Two of the products--7,17(S)- and 10,17(S)-dihydro(pero)xy-DHA [7,17- and 10,17-diH(P)DHA]--were formed from soybean 15-LOX-derived 17(S)-hydro(pero)xy-DHA [17(S)-H(P)DHA], whereas t...
