Membrane phospholipids can function as potent regulators of ion channel function. This study uncovers and investigates the effect of phosphatidic acid on Kv channel gating. Using the method of reconstitution into planar lipid bilayers, in which protein and lipid components are defined and controlled, we characterize two effects of phosphatidic acid. The first is a non-specific electrostatic inf...
An early response to epidermal growth factor in A431 cells is the generation of diglyceride, a physiological activator of protein kinase C. By differentially prelabeling cellular phospholipids with [3H]arachidonate and [3H]myristate, which are incorporated primarily into phosphatidylinositol and phosphatidylcholine, respectively, we have found that epidermal growth factor induces an increase in...
The lipid phosphatidic acid is an important metabolic intermediate in the biosynthesis of lipids in all eukaryotic cells, but it is even more than that. Phosphatidic acid is emerging as a lipid that is both composer and conductor, where in addition to its role as biosynthetic precursor (composer) it is also a potent signaling molecule (conductor) that integrates membrane biogenesis with nutrien...
Final step of phosphatidic Acid synthesis in pea chloroplasts occurs in the inner envelope membrane.
The second enzyme of phosphatidic acid synthesis from glycerol-3-phosphate, 1-acylglycerophospate acyltransferase, was localized to the inner envelope membrane of pea chloroplasts. The activity of this enzyme was measured by both a coupled enzyme assay and a direct enzyme assay. Using the coupled enzyme assay, phosphatidic acid phosphatase was also localized to the inner envelope membrane, alth...
