Sub-cellular localization and some properties of 13-hydroperoxide-specific divinyl ether synthase from garlic bulbs were studied. Sub-cellular fractions from garlic bulbs were incubated with [1-(14)C](9Z,11E,13S)-13-hydroperoxy-9,11-octadecadienoic acid (13-HPOD). The predominant part of divinyl
The microsomal fraction of homogenate of garlic (Allium sativum L.) bulbs contains a divinyl ether synthase which catalyzes conversion of (9Z,11E,13S)-13-hydroperoxy-9, 11-octadecadienoic acid and (9Z,11E,13S,15Z)-13-hydroperoxy-9,11,15-octadecatri eno ic acid into
Formation of 13-lipoxygenase-derived divinyl ethers has been described in garlic bulbs. Here, the identification of a cDNA from garlic is described, which encodes for an enzyme that corresponds to divinyl ether synthases (DES). The recombinant protein was expressed in Escherichia coli and shown to
Incubations of [1-14C]linoleic acid or [1-14C]-(9Z,11E, 13S)-13-hydropero xy-9,11-octadecadienoic acid (13-HPOD) with juice of garlic bulbs lead to the formation of one predominant labelled product, viz., the novel divinyl ether (9Z,11E, 1'E)-12-(1'-hexenyloxy)-9,11-dodecadienoic acid ('etheroleic
