additional information

Ranunculus acris

preferred substrates of the enzyme are the 13-hydroperoxides of alpha-linolenic and linoleic acids, which are converted to the divinyl ether oxylipins (omega5Z)-etherolenic acid, (9Z,11E)-12-[(1?Z,3?Z)-hexadienyloxy]-9,11-dodecadienoic acid, and (omega5Z)-etheroleic acid, (9Z,11E)-12-[(1?Z)-hexenyloxy]-9,11-dodecadienoic acid, respectively, as revealed by the data of mass spectrometry, NMR and UV spectroscopy
