Phosphatidic Acid Synthesis in Yeast.
1. The presence of palmitoyl-CoA-l-glycerol 1-phosphate palmitoyltransferase (EC2.3.1.15) has been demonstrated in a particulate fraction of baker's yeast. 2. The enzyme has been characterized, and its activity studied as a function of pH and concentration of substrates. 3. Inhibition by thiol poisons and protection by acyl-CoA have been used to obtain information on the active site. 4. By vari...
متن کاملPhosphatidic acid synthesis in Escherichia coli.
The kinetic properties of acyl-coenzyme A (CoA): l-alpha-glycerol-phosphate trans-acylase (EC 2.3.1.15) from Escherichia coli were studied. At 10 C, a temperature at which the reaction was proportional to time and enzyme concentration, the enzyme had an apparent K(m) of 60 mum for l-alpha-glycerol-phosphate. The curve describing the velocity of the reaction as a function of palmitoyl-CoA concen...
متن کاملRole of phosphatidic acid in plant galactolipid synthesis.
Phosphatidic acid (PA) is a precursor metabolite for phosphoglycerolipids and also for galactoglycerolipids, which are essential lipids for formation of plant membranes. PA has in addition a main regulatory role in a number of developmental processes notably in the response of the plant to environmental stresses. We review here the different pools of PA dispatched at different locations in the ...
متن کاملPhosphatidic Acid and Glyceride Synthesis by Particles from Spinach Leaves.
For many years it has been recognized that particulate bodies within cells capable of carrying out energy transductions contain large quantities of lipids which include significant amounts of phosphatides, glycolipids, quinones, pigments and certain lipid soluble vitamins. A great deal of conjecture has been written concerning the possible role of lipids, especially those with amphipathic prope...
متن کاملPhosphatidic Acid, Lysophosphatidic Acid and Related Lipids
Phosphatidic acid or 1,2-diacyl-sn-glycero-3-phosphate is not an abundant lipid constituent of any living organism to my knowledge, but it is extremely important as an intermediate in the biosynthesis of triacylglycerols and phospholipids and as a signalling molecule. Indeed, it is often over-estimated in tissues as it can arise by inadvertent enzymatic hydrolysis during inappropriate storage o...
