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)
