UniprotKB/SwissProt ID: O48723 (O48723)
Gene Name:
PLP2
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Possesses non-specific lipolytic acyl hydrolase (LAH) activity. Catalyzes the hydrolysis of the galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG), and less efficiently the phoshpolipids phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidic acid (PA), phosphatidylserine (PS) and phosphatidylinositol (PI). Favors the release of fatty acid at the sn-1 position for PC or PE and the sn-2 position for PG, PA, PS and PI. Negatively affects disease resistance to the necrotic fungal pathogen Botrytis cinerea and the avirulent bacteria Pseudomonas syringae by promoting cell death and reducing the efficiency of the hypersensitive response, respectively. However, PLP2 contributes to resistance to cucumber mosaic virus (CMV), an obligate parasite inducing hypersensitive response. May negatively regulate oxylipin production, possibly via participating in membrane repair that includes removal of oxidatively modified lipids
