The chemical nature of the products obtained by the action of cabbage-leaf phospholipase D on lysolecithin: the structure of lysolecithin.
1. Lysolecithin, prepared by the action of snake-venom phospholipase A on ovolecithin, when incubated with Savoy-cabbage phospholipase D, in the presence of Ca(2+) ions, gave two degradation products (designated A and B) in the form of their calcium salts. 2. These calcium salts were separated quantitatively by solvent fractionation and converted into the corresponding sodium salts. 3. Substanc...
متن کاملFactors Affecting the Hemolytic Action of "lysolecithin" upon Rabbit Erythrocytes
1. Lysolipid was prepared by the action of snake venom on egg yolk, and a study was made of the factors affecting its hemolytic action upon rabbit erythrocytes. 2. Lysis proceeded very rapidly at first, then ceased within a few minutes at room temperature. A given amount of lysin appeared to hemolyze a fixed number of cells, under specified conditions. 3. The more dilute erythrocyte suspensions...
متن کاملExpression of Phospholipase D during Castor Bean Leaf Senescence.
Membrane deterioration in plant senescence is commonly associated with progressive decreases in membrane phospholipid content. This study investigated the expression and regulation of phospholipase D (PLD; EC 3.1.4.4) during senescence in castor bean (Ricinus communis L. cv Hale) leaf discs. The rate of leaf senescence was accelerated by 50 [mu]M abscisic acid and was attenuated by 50 [mu]M cyt...
متن کاملXxiii . the Ether - Soluble Substances of Cabbage Leaf Cytoplasm
IN a series of papers [Chibnall and Channon, 1927, 1, 2, 3; Channon and Chibnall, 1927], we have recorded certain results which we have obtained in the analysis of the ether extract of the leaf-cell cytoplasm of the cabbage. The object of the present paper is to discuss these results so far as is at present possible from their chemical and physiological aspects, and, in passing, to refer to our...
متن کاملAction of Phospholipase C on the Thyroid
Treatment of dog thyroid slices with an enzyme present in the growth medium of Clostridium perjringens makes them unresponsive to thyroid-stimulating hormone (TSH) as measured by the oxidation of glucose-1J4C to 14C02. This enzyme appears to be phospholipase C since (a) both the anti-TSH effect and the phospholipase activity are inseparable over a 240-fold purification, (b) both activities are ...
