Castor bean phospholipase

Wang X, Dyer JH, Zheng L Purification and immunological analysis of phospholipase D from castor bean endosperm. Arch Biochem Biophys 306 486-494 (1993). 

Biochemical characteristics of purified PLD are alike to most of the plant soluble phospholipase D (TABLB II) concerning the pH optimum, pi and mol. wt. (denaturing conditions) and differes in native mol.wt. and higher concentration of activators is demanded. In the contrast with results published for PLD from Castor bean endosperm (5), rape seed PLD seems to be a monomeric protein.
