Protein

Phospholipase D alpha 2

Gene

PLDALPHA2

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Hydrolyzes glycerol-phospholipids at the terminal phosphodiesteric bond. Plays an important role in various cellular processes, including phytohormone action and response to stress, characterized by acidification of the cell.

Catalytic activityi

A phosphatidylcholine + H2O = choline + a phosphatidate.

Cofactori

Calcium. Calcium requirement for activity depends on pH. Active either under acidic conditions with micromolar levels of calcium (PIP2-dependent) or at neutral pH with millimolar levels of calcium (PIP2-independent).

Note: Found in vacuoles and also associated with plasma, microsomal and mitochondrial membranes and in clathrin-coated vesicles. Not found in chloroplast or nuclei. Activation increases association of preexisting enzyme with membranes. The distribution of this conventional PLD between membrane-associated and soluble fractions varied from organ to organ and is calcium-regulated.

Domaini

C2 domain is a calcium-binding fold, and the binding promotes the protein association with membranes. A lower affinity toward calcium can be anticipated for PLD alpha due to the absence of two potential calcium ligands.
