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 + O(2) = (9Z,11E)-(13S)-13-hydroperoxyoctadeca-9,11-dienoate.
Cofactor	Binds 1 iron ion per subunit. Iron is tightly bound By similarity.
Pathway	Lipid metabolism; oxylipin biosynthesis.
Subunit structure	Monomer By similarity.
Subcellular location	Cytoplasm.
Tissue specificity	Fruit specific.
Sequence similarities	Belongs to the lipoxygenase family. Contains 1 lipoxygenase domain. Contains 1 PLAT domain.
