In isolated inner medullary collecting duct (IMCD) cells requirements for the organic osmolyte glycerophosphorylcholine (GPC) vary with extracellular osmolality. To investigate mechanisms of osmotic adaptation GPC metabolism was studied under different osmotic conditions. In contrast to the GPC precursors choline

The functional interaction of the estrogen-induced uterine enzyme glycerylphosphorylcholine (GPC) diesterase with epididymal rat sperm before and after incubation under capacitating conditions was investigated indirectly, by measuring the glycerol phosphate (GP) released on enzymatic hydrolysis of GPC and using oxygen
Inhibition of a Zn(2+)-glycerophosphocholine cholinephosphodiesterase by thiols or tellurites were examined mechanistically. Inactivation of the phosphodiesterase by thio-carboxylates, which was due to the removal of Zn2+ in the catalytic site, was enhanced by introduction of an amino group in the

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 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
