Phosphatase enzymes are also used by soil microorganisms to access organically bound phosphate nutrients. An assay on the rates of activity of these enzymes may be used to ascertain biological demand for phosphates in the soil. Some plant roots, especially cluster roots, exude carboxylates that perform acid phosphatase activity, helping to ...
Lysophosphatidic acid phosphatase type 6 is an acid phosphatase enzyme that is encoded in humans by the ACP6 gene. [5] [6]It acts as a phosphomonoesterase at low pHs. [7] It is responsible for the hydrolysis of Lysophosphatidic acids (LPAs) to their respective monoacylglycerols and the release a free phosphate group in the process. [8]
Phosphoric monoester hydrolases (or phosphomonoesterases) are enzymes that catalyse the hydrolysis of O-P bonds by nucleophilic attack of phosphorus by cysteine residues or coordinated metal ions.
Tartrate-resistant acid phosphatase (TRAP or TRAPase), also called acid phosphatase 5, tartrate resistant (ACP5), is a glycosylated monomeric metalloprotein enzyme expressed in mammals. [5] It has a molecular weight of approximately 35kDa, a basic isoelectric point (7.6–9.5), and optimal activity in acidic conditions.
A protein phosphatase is an enzyme that dephosphorylates an amino acid residue of its protein substrate. Whereas protein kinases act as signaling molecules by phosphorylating proteins, phosphatases remove the phosphate group, which is essential if the system of intracellular signaling is to be able to reset for future use.
Lysosomal acid phosphatase is composed of two subunits, alpha and beta, and is chemically and genetically distinct from red cell acid phosphatase. Lysosomal acid phosphatase 2 is a member of a family of distinct isoenzymes which hydrolyze orthophosphoric monoesters to alcohol and phosphate. Acid phosphatase deficiency is caused by mutations in ...
Caustis blakei is a slow-growing plant that has adapted to acidic, sandy soils that have high levels of iron and low levels of phosphorus. [4] As a result, it is capable of inducing dauciform roots as a morphological response to growing in soil that is deficient of these essential minerals.
The product of this gene belongs to the phosphotyrosine protein phosphatase family of proteins. It functions as an acid phosphatase and a protein tyrosine phosphatase by hydrolyzing protein tyrosine phosphate to protein tyrosine and orthophosphate. This enzyme also hydrolyzes orthophosphoric monoesters to alcohol and orthophosphate.
