| choline phosphatase | <enzyme> An enzyme found mostly in plant tissue. It hydrolyzes glycerophosphatidates with the formation of a phosphatidic acid and a nitrogenous base such as choline. This enzyme also catalyses transphosphatidylation reactions. Chemical name: Phosphatidylcholine phosphatidohydrolase Registry number: EC 3.1.4.4 (12 Dec 1998) |
|---|---|
| RNA-tyrosine phosphatase | <enzyme> Hela cell enzyme which removes 5'-terminal protein from poliovirus RNA by breaking the tyrosine-phosphate bond between the above two entities Registry number: EC 3.1.4.- Synonym: uridylyl-(5'p-o)-tyrosine phosphodiesterase, y-pupnpde, tyrosine-RNA phosphatase, uridylylpolynucleotide-(5'p-o)-tyrosine phosphodiesterase (26 Jun 1999) |
| chromatin 3'-phosphatase-5'-hydroxy kinase | <enzyme> Hydrolyzes the 3'-phosphate end of a polynucleotide duplex followed by ATP-mediated phosphorylation of the 5'-oh end Registry number: EC 3.1.3.- Synonym: chromatin-phosphatase-hydroxykinase (26 Jun 1999) |
| phenylalanine hydroxylase phosphatase | <enzyme> Catalyses dephosphorylation of phosphorylated phenylalanine hydroxylase Registry number: EC 3.1.3.- Synonym: phe hydroxylase phosphatase (26 Jun 1999) |
| microtubule-associated protein-2 phosphatase | <enzyme> does not fit into any of the classes of protein phosphatases (types 1,2a,2b and 2c) involved in cellular regulation Registry number: EC 3.1.3.- Synonym: map-2 phosphatase (26 Jun 1999) |
| phosphatase | <enzyme> That hydrolyse phosphomonoesters. Acid phosphatases are specific for the single charged phosphate group and alkaline phosphatases for the double charged group. These specificities do not overlap. The phosphatases comprise a very wide range of enzymes including broad and narrow specificity members. Phosphoprotein phosphatases specifically de phosphorylate a particular protein and are essential if phosphorylation is to be used as a reversible control system. (31 Dec 1997) |

| phosphatidate phosphatase | <enzyme> A phosphomonoesterase involved in the synthesis of triacylglycerols. It catalyses the hydrolysis of phosphatidates with the formation of diacylglycerols and orthophosphate. Chemical name: 3-sn-Phosphatidate phosphohydrolase Registry number: EC 3.1.3.4 (12 Dec 1998) |
| phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase | <enzyme> Hydrolyzes the 5-position phosphate of ptdins(3,4,5)p3 forming phosphatidylinositol-3,4-bisphosphate; an isoenzyme forms a complex with the p85/p110 form of pi 3-kinase Registry number: EC 3.1.3.- Synonym: ptdins(3,4,5)p3 5-phosphatase, pi(3,4,5)p3 5-pase (26 Jun 1999) |
| phosphatidylinositol-3-phosphatase | <enzyme> Hydrolyzes phosphatidylinositol 3-phosphate in nih 3t3 cells; specific as it has little or no activity on the monoester phosphates of ptdins(4)p, ptdins(4,5)p2, or inositol 1,3-bisphosphate; does not require added metal ions for activity and is maximally active in the presence of edta; inhibited by ca(2+), mg(2+),zn(2+), and the phosphatase inhibitor vo(3-)4 Registry number: EC 3.1.3.64 Synonym: phosphatidylinositol 3-phosphatase (26 Jun 1999) |
| phosphatidylinositol 4-phosphate phosphatase | <enzyme> From human erythrocyte membranes Registry number: EC 3.1.3.- Synonym: ptdins-4p-phosphatase, phosphatidylinositol-4-phosphate monoesterase, ptdins4p monoesterase (26 Jun 1999) |
| phosphocholine phosphatase | <enzyme> Unlike alkaline phosphatase the hamster heart enzyme has a different pH optimum and heat sensitivity and is not inhibited by amino acids Registry number: EC 3.1.3.- (26 Jun 1999) |
| phosphofructokinase phosphatase | <enzyme> May be an aspect of EC 3.1.3.16 Registry number: EC 3.1.3.- Synonym: pfk-inactivating enzyme (26 Jun 1999) |
