Localization of D-myoinositol 1:2-cyclic phosphate 2-phosphohydrolase in rat kidney.
1. On subcellular fractionation of rat kidney homogenates by differential and density-gradient centrifugation, the bulk of the inositol 1:2-cyclic phosphate 2-phosphohydrolase activity remains with the alkaline phosphatase activity, suggesting localization in the brush borders of the proximal tubules. 2. Histochemical studies with a medium containing inositol 1:2-cyclic phosphate and Escherichi...
متن کاملCharacterization of murine sphingosine-1-phosphate phosphohydrolase.
In the present study we have characterized mammalian sphingosine-1-phosphate phosphohydrolase (SPP1), an enzyme that specifically dephosphorylates sphingosine 1-phosphate (S1P) and which differs from previously described lipid phosphate phosphohydrolases. Based on sequence homology to murine SPP1, we cloned the human homolog. Transfection of human embryonic kidney 293 and Chinese hamster ovary ...
متن کاملA colorimetric determination of inositol monophosphates as an assay for D-glucose 6-phosphate-1L-myoinositol 1-phosphate cyclase.
A rapid and convenient chemical assay for the enzyme d-glucose 6-phosphate-1l-myoinositol 1-phosphate cyclase is described. The 1l-myoinositol 1-phosphate formed enzymically was oxidized with periodic acid liberating inorganic phosphate, which was assayed. myoInositol 2-phosphate can be assayed in the same way. Glucose 6-phosphate and other primary phosphate esters gave only very small quantiti...
متن کاملCJ-21,164, a new D-glucose-6-phosphate phosphohydrolase inhibitor produced by a fungus Chloridium sp.
A new D-glucose-6-phosphate phosphohydrolase (G6Pase) inhibitor, CJ-21,164 (1) was isolated from the fermentation broth of the fungus Chloridium sp. CL48903. The structure was elucidated to be a novel tetramer of the salicylic acid derivatives by spectroscopic analyses. Compound I inhibited G6Pase in rat liver microsomes with an IC50 of 1.6 microM. Glucose output from hepatocytes isolated from ...
متن کاملPulmonary phosphatidic acid phosphatase and lipid phosphate phosphohydrolase.
The lung contains two distinct forms of phosphatidic acid phosphatase (PAP). PAP1 is a cytosolic enzyme that is activated through fatty acid-induced translocation to the endoplasmic reticulum, where it converts phosphatidic acid (PA) to diacylglycerol (DAG) for the biosynthesis of phospholipids and neutral lipids. PAP1 is Mg(2+) dependent and sulfhydryl reagent sensitive. PAP2 is a six-transmem...
