Aplicação

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).

Ações bioquímicas/fisiológicas

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

Definição da unidade

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.

forma física

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

Nota de preparo

Prepared by ion exchange chromatography and hydrophobic interaction chromatography.

Nota de análise

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
