D010706 |
[An organothiophosphorus insecticide that has been used to control pig mange.

|
Phosphate Acetyltransferase
|
D010709 |
[An enzyme that catalyzes the synthesis of acetylphosphate from acetyl-CoA and inorganic phosphate. Acetylphosphate serves as a high-energy phosphate compound. EC 2.3.1.8.

Phosphate Transport Proteins
|
D028061 |
[Membrane proteins that are involved in the active transport of phosphate.

D010710 |
[Inorganic salts of phosphoric acid.

|
Phosphatidate Phosphatase
|
D010711 |
[A phosphomonoesterase involved in the synthesis of triacylglycerols. It catalyzes the hydrolysis of phosphatidates with the formation of diacylglycerols and orthophosphate. EC 3.1.3.4.

|
Phosphatidic Acids
|
D010712 |
[Fatty acid derivatives of glycerophosphates. They are composed of glycerol bound in ester linkage with 1 mole of phosphoric acid at the terminal 3-hydroxyl group and with 2 moles of fatty acids at the other two hydroxyl groups.

|
Phosphatidyl-N-Methylethanolamine N-Methyltransferase
|
D050941 |
[An enzyme that catalyzes the METHYLATION of phosphatidyl-N-methylethanolamine to produce phosphatidyl-N-dimethylethanolamine. This enzyme can also methylate phosphatidyl-N-dimethylethanolamine to produce phosphatidyl-N-trimethylethanolamine (PHOSPHATIDYLCHOLINE).
] |
|
Phosphatidylcholine-Sterol O-Acyltransferase
|
D007862 |
[An enzyme secreted from the liver into the plasma of many mammalian species. It catalyzes the esterification of the hydroxyl group of lipoprotein cholesterol by the transfer of a fatty acid from the C-2 position of lecithin. In familial lecithin:cholesterol acyltransferase deficiency disease, the absence of the enzyme results in an excess of unesterified cholesterol in plasma.

|
Phosphatidylcholines
|
D010713 |
[Derivatives of PHOSPHATIDIC ACIDS in which the phosphoric acid is bound in ester linkage to a CHOLINE moiety.
] |
|
Phosphatidylethanolamine Binding Protein
|
D049488 |
[A ubiquitously found basic protein that binds to phosphatidylethanolamine and NUCLEOTIDES. It is an endogenous inhibitor of RAF KINASES and may play a role in regulating SIGNAL TRANSDUCTION. Phosphatidylethanolamine-binding protein is the precursor of hippocampal cholinergic neurostimulating peptide, which is cleaved from the N-terminal region of the protein.

|
Phosphatidylethanolamine N-Methyltransferase
|
D050918 |
[An enzyme that catalyses three sequential METHYLATION reactions for conversion of phosphatidylethanolamine to PHOSPHATIDYLCHOLINE.
] |
|
Phosphatidylethanolamines
|
D010714 |
[Derivatives of phosphatidic acids in which the phosphoric acid is bound in ester linkage to an ethanolamine moiety. Complete hydrolysis yields 1 mole of glycerol, phosphoric acid and ethanolamine and 2 moles of fatty acids.
] |
|
Phosphatidylglycerols
|
D010715 |
[A nitrogen-free class of lipids present in animal and particularly plant tissues and composed of one mole of glycerol and 1 or 2 moles of phosphatidic acid. Members of this group differ from one another in the nature of the fatty acids released on hydrolysis.
] |
|
Phosphatidylinositol 3-Kinase
|
D058539 |
[A phosphatidylinositol 3-kinase that catalyzes the conversion of 1-phosphatidylinositol into 1-phosphatidylinositol 3-phosphate.
] |
|
Phosphatidylinositol 3-Kinases
|
D019869 |
[Phosphotransferases that catalyzes the conversion of 1-phosphatidylinositol to 1-phosphatidylinositol 3-phosphate. Many members of this enzyme class are involved in RECEPTOR MEDIATED SIGNAL TRANSDUCTION and regulation of vesicular transport with the cell. Phosphatidylinositol 3-Kinases have been classified both according to their substrate specificity and their mode of action within the cell.
] |
|
Phosphatidylinositol 4,5-Diphosphate
|
D019269 |
[A phosphoinositide present in all eukaryotic cells, particularly in the plasma membrane. It is the major substrate for receptor-stimulated phosphoinositidase C, with the consequent formation of inositol 1,4,5-triphosphate and diacylglycerol, and probably also for receptor-stimulated inositol phospholipid 3-kinase.
