What is apyrase?

Apyrase is an enzyme that catalyzes the hydrolysis of ATP and ADP into AMP and inorganic phosphate. It plays an important role in regulating the levels of extracellular ATP and ADP, which are important signaling molecules in various physiological processes.

Apyrase is found in a variety of organisms, including bacteria, plants, and animals. In humans, apyrase is present in platelets and endothelial cells, where it helps regulate platelet aggregation and hemostasis.

In addition to its role in regulating extracellular nucleotide levels, apyrase has also been implicated in immune responses, inflammation, and cardiovascular diseases. Researchers are investigating the potential therapeutic applications of apyrase in various medical conditions.

Overall, apyrase is an important enzyme that plays a critical role in maintaining cellular homeostasis and regulating extracellular signaling pathways.
