Application

Lipoxidase, or lipoxygenase, from Glycine max (soybean) has been used for the modification of low density lipoprotein, isolated from human plasma.
The soybean enzyme will use arachidonic acid as a substrate, with ~ 15% of the activity indicated using linoleic acid as the substrate; the product of arachidonic acid oxidation is 12- or 15-hydroperoxyarachidonic acid (12-HPETE or 15-HPETE).

Actions biochimiques/physiologiques

Catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure.

Définition de l'unité

One unit will cause an increase in A234 of 0.001 per min at pH 9.0 at 25 °C when linoleic acid is the substrate in 3.0 ml volume (1 cm light path). One A234 unit is equivalent to the oxidation of 0.12 μmole of linoleic acid.

Forme physique

Suspension in 2.3 M (NH4)2SO4 solution, pH approx. 6.0

Notes préparatoires

Prepared by ion exchange chromatography and hydrophobic interaction chromatography.

Remarque sur l'analyse

Protein determined by biuret.

The lipid precursor alcohols of pyrethrins-jasmolone, pyrethrolone and cinerolone-have been proposed as sharing parts of the oxylipin pathway with jasmonic acid. This implies that one of the first committed steps of pyrethrin biosynthesis is catalyzed by a lipoxygenase, catalyzing the

We studied the effect of in vitro moderate oxidation on low density lipoprotein (LDL) conformation and metabolism. LDL was modified with either copper ions or phospholipase A2 plus lipoxygenase and, in both cases, mild oxidative conditions were used. The resulting

A catalytic asymmetric synthesis of (S)-(-)-zearalenone is reported using asymmetric allylic alkylation for the introduction of the stereocenter. (S)-(-)-Zearalenone turned out to be a novel lipoxygenase inhibitor.

Oxidative modification of low density lipoprotein is believed to be an important pathway by which the lipoprotein becomes atherogenic. The in vitro systems for oxidative modification of low density lipoprotein thus far described all appear to depend upon the presence
