Possesses non-specific lipolytic acyl hydrolase (LAH) activity. Hydrolyzes phospholipids as well as galactolipids. May play a role in disease resistance (By similarity). The nitrogen atoms of the two glycine residues in the GGXR motif define the oxyanion hole, and stabilize the oxyanion that forms during the nucleophilic attack by the catalytic serine during substrate cleavage. Belongs to the patatin family.
