Protein

Lipoxygenase 2.1, chloroplastic

Gene

LOX2.1

Organism
Hordeum vulgare (Barley)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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. This enzyme is possibly involved in jasmonic acid synthesis. It exhibits linoleate 13-lipoxygenase and arachidonate 15-lipoxygenase activity.1 Publication

Catalytic activityi

Linoleate + O2 = (9Z,11E,13S)-13-hydroperoxyoctadeca-9,11-dienoate.1 Publication
Alpha-linolenate + O2 = (9Z,11E,13S,15Z)-13-hydroperoxyoctadeca-9,11,15-trienoate.1 Publication

Cofactori

Fe cationPROSITE-ProRule annotationNote: Binds 1 Fe cation per subunit. Iron is tightly bound.PROSITE-ProRule annotation

pH dependencei

Optimum pH is 7.
