In pericytes from bovine retina, the enzyme glycerophosphocholine phosphodiesterase, catalyzing the hydrolysis of sn-glycero-3-phosphocholine to glycero-3-phosphate and choline, has been characterized with respect to pH optimum, metal ion dependence, Km, inhibitors, and subcellular localization. In these cells, the natural substrate

The product of the open reading frame YPL206c, Pgc1p, of the yeast Saccharomyces cerevisiae displays homology to bacterial and mammalian glycerophosphodiester phosphodiesterases. Deletion of PGC1 causes an accumulation of the anionic phospholipid, phosphatidylglycerol (PG), especially under conditions of inositol limitation.

In microvessels isolated from bovine brain, microsomal enzyme activities involved in phosphatidylcholine biosynthesis and degradation were determined. The microvessels possessed acyl-CoA:1-acyl-sn-glycero-3-phosphocholine (AT) and glycerophosphocholine phosphodiesterase (GroPChoPDE) activity at a higher level compared with bovine and rat brain or rat liver

An enzyme releasing phosphocholine from glycerophosphocholine was purified to apparent homogeneity based upon SDS-PAGE. The enzyme was liberated from lyophilized bovine myelin by differential detergent extraction and final purification was accomplished with Q-Sepharose Fast Flow chromatography yielding an apparently homogeneous

Previous studies have demonstrated elevated brain levels of phosphomonoesters in early stages of Alzheimer's disease and elevations of phosphodiesters later in the disease. In addition, preliminary quantitative analyses of the phospholipids of Alzheimer's brain reveals either decreases in some phospholipids
