Acid phosphatase (EC 3.1.3.2, systematic name phosphate-monoester phosphohydrolase (acid optimum)) is an enzyme that frees attached phosphoryl groups from other molecules during digestion. It can be further classified as a phosphomonoesterase.

2022年11月14日 · Acid phosphatase is an enzyme that catalyzes the hydrolysis of phosphate esters in an acidic environment. This chemical reaction is essential to different metabolic processes. Therefore, acid phosphatase exists in several biological kingdoms, including plants, animals, fungi, and bacteria.

Acid phosphatases (APs) are a family of enzymes that belong to the hydrolase class. They are specifically grouped together because of the shared ability to catalyse the hydrolysis of orthophosphate monoesters under acidic conditions.

Acid phosphatases can be defined as enzymes that hydrolyze monophosphate esters in a two-step mechanism. They lack metal-ion cofactors and involve a covalent phosphoryl-enzyme and a non-covalent enzyme-inorganic phosphate complex.

Acid phosphatase, or phosphomonoesterase, is an enzyme that removes phosphate groups from phosphorylated molecules. In activated macrophages or dendritic cells, acid phosphatase triggers a drop in the internal pH of macrophage phagolysosomes, increasing their internal acidity.

During this experiment, you will investigate the properties of an acid phosphatase from wheat germ. Acid phosphatases have optimal activity at pH values from 4 to 6, and are distinct from alkaline phosphatases with optimal activity in the pH range of 8-9.

Acid phosphatases (EC 3.1.3.2) are the enzymes that catalyse transphosphorylation reactions and promotes the hydrolysis of numerous orthophosphate esters in acidic media, as a crucial element for the metabolism of phosphate in tissues.

2012年6月10日 · Acid phosphatase (AP) (orthophosphoric-monoester phosphohydrolase, EC 3.1.3.2) catalyzes hydrolysis of phosphate monoesters in acidic condition with pH 4–7 [1] [Fig. 1]. Few members of AP family are metallohydrolase having two heterovalent metal ions in …

Therefore, acid phosphatase exists in several biological kingdoms, including plants, animals, fungi, and bacteria.

The reaction catalyzed by PAH1 -encoded PAP (highlighted in yellow) is shown. Regulation of PAP activity plays a role in governing whether cells synthesize membrane phospholipids via CDP-DAG or DAG.
