Descripción general

Lipoxidases (LOXs), or lipoxygenases, are nonheme iron proteins. Lipoxygenases are widely present in plants, some microorganisms, and animals. They are categorized as LOX-1, LOX-2, and LOX-3 with respect to pH and optimum temperature, substrate specificity, and level of inhibition by different agents.

Aplicación

Lipoxidase from Glycine max (soybean) has been used:
  • to study the effects of 2-(α-D-glucopyranosyl)methyl-2,5,7,8-tetramethylchroman-6-ol(TMG) on oxidation of lipoproteins
  • as a representative enzyme for lipoxygenases in microplate assay platform to screen for enzymes degrading wood extractives
  • as a positive control in lipoxygenase inhibitory activity assay

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).

Acciones bioquímicas o fisiológicas

Catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure.
Lipoxidases are deactivated by heat treatment near 100°C for 5 to 10 minutes. Studies show that gamma irradiation treatment decreases the specific activity of soybean lipoxygenases. These enzymes are used in studies related to asthma and allergies. Lipoxidases are applicable for industrial bio-transformations such as in the production of aroma fine chemicals.

Definición de unidad

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.

Allene oxide cyclase (AOC) is a key enzyme in the jasmonic acid (JA) biosynthetic pathway in plants, during which it catalyzes stereospecific conversion of 12,13(S)-epoxy-9(Z),11,15(Z)-octadecatrienoic acid (12,13-EOT) to cis(+)-12-oxophytodienoic acid. Here, rice allene oxide cyclase (OsAOC) was localized to the
