General annotation (Comments)

Function

Plant lipoxygenase may be involved in a number of diverse aspects of plant physiology including growth and development, pest resistance, and senescence or responses to wounding. It catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure.

Catalytic activity

Linoleate + O2 = (9S,10E,12Z)-9-hydroperoxy-10,12-octadecadienoate.

Cofactor

Binds 1 iron ion per subunit. Iron is tightly bound By similarity.

Pathway

Lipid metabolism; oxylipin biosynthesis.

Subunit structure

Monomer.

Subcellular location

Cytoplasm.

Miscellaneous

Soybean contains at least 4 distinct isoenzymes, L-1, L-2, L-3a and L-3b in dry seeds, and at least two distinct isozymes in the hypocotyl/radicle region of the seedling stem.

Sequence similarities

Belongs to the lipoxygenase family.

Contains 1 lipoxygenase domain.

Contains 1 PLAT domain.
