General annotation (Comments)

Function	Specifically cleaves olefinic bonds in alpha,beta-unsaturated carbonyls and may be involved in detoxification or modification of these reactive compounds. May be involved in the biosynthesis or metabolism of oxylipin signaling molecules. In vitro, reduces 9R,13R-12-oxophyodienoic acid (9R,13R-OPDA) to 9R,13R-OPC-8:0, but not 9S,13S-OPDA, the natural precursor of jasmonic acid. Also reduces N-ethylmaleimide and maleic acid. Ref.2
Catalytic activity	8-((1R,2R)-3-oxo-2-((Z)-pent-2-enyl)cyclopentyl)octanoate + NADP+ = (15Z)-12-oxophyto-10,15-dienoate + NADPH. Ref.1
Cofactor	FMN. Ref.2 Ref.3
Pathway	Lipid metabolism; oxylipin biosynthesis.
Subcellular location	Cytoplasm. Ref.2
Tissue specificity	Constitutively expressed in roots, leaves, cotyledons, cells culture and to lower extend in flowers. Ref.1
Induction	Seems to not be influenced by wounding.
Sequence similarities	Belongs to the NADH:flavin oxidoreductase/NADH oxidase family.
biophysicochemical properties	Kinetic parameters: The highest catalytic efficiency was observed with N-ethylmaleimide. KM=8 µM for N-ethylmaleimide (at pH 7.0 and 25 degrees Celsius) KM=47 µM for maleic acid (at pH 7.0 and 25 degrees Celsius) KM=15 µM for OPDA (at pH 7.0 and 25 degrees Celsius)
