| Gomori's non-specific acid phosphatase stain | <technique> A method in which formalin-fixed frozen sections are incubated in a substrate containing sodium beta-glycerophosphate and lead nitrate at pH 5.0; the insoluble lead phosphate produced is treated with ammonium sulfide to give a black lead sulfide. (05 Mar 2000) |
| RLK5-associated protein phosphatase | <enzyme> Associated with serine-threonine receptor-like kinase, rlk5; from arabidopsis thaliana; composed of 3 domains, an amino-terminal signal anchor, a kinase interaction domain and a type 2c protein phosphatase catalytic domain; mw 65 kD; genbank u09505 Registry number: EC 3.1.3.- Synonym: kapp, kinase-associated protein phosphatase (26 Jun 1999) |
| 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) |

| 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) |
