IntEnz Enzyme Nomenclature


Accepted name:
linolenate 9R-lipoxygenase
Other names:
linoleate 9R-dioxygenase
Systematic name:
α-linolenate:oxygen (9R)-oxidoreductase



In cyanobacteria the enzyme is involved in oxylipin biosynthesis. The enzyme also converts linoleate to (9R,10E,12Z)-9-hydroperoxyoctadeca-10,12-dienoate.
