Cyclooxygenase - Wikipedia
Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, EC 1.14.99.1) that is responsible for biosynthesis of prostanoids, including thromboxane and prostaglandins such as …
Cyclooxygenase (COX) Enzymes, Inhibitors, and More
2024年5月27日 · Cyclooxygenase (COX) is an enzyme that forms prostaglandins, prostacyclins, and thromboxanes —substances called "prostanoids" that are responsible for the inflammatory response. If you have ever experienced inflammation-related pain—for example, due to arthritis—you've felt cyclooxygenase at work.

Cyclooxygenase (COX; prostaglandin G/H synthase, EC 1.14.99.1) catalyzes the first two steps in the biosynthesis of prostaglandins (PGs). The two COX isoforms COX-1 and COX-2 are the targets of the widely used nonsteroidal anti-inflammatory drugs, ...
Cyclooxygenase - an overview | ScienceDirect Topics
Cyclooxygenase (COX) is the rate-limiting enzyme in the synthesis of biological mediators termed prostanoids, consisting of prostaglandin PGD 2, PGE 2, PGF 2α, prostacyclin PGI 2, and thromboxane TXA 2.
Cyclooxygenase enzymes: regulation and function - PubMed
This review discusses: 1) how two separate catalytic processes in COX - peroxidase and prostaglandin synthase - act in an integrated fashion manner to generate prostaglandins; 2) why irreversible inactivation of COX is important constitutively and pharmacologically; 3) how cells have managed to use two closely related, almost identical enzymes i...
Cyclooxygenase - an overview | ScienceDirect Topics
Cyclooxygenase (COX) is a rate-limiting enzyme involved in the conversion of arachidonic acid to prostaglandin H 2, which is the precursor of several molecules, including prostaglandins, prostacyclin, and thromboxanes. It consists of at least two …
Cyclooxygenase-1 - Wikipedia
Cyclooxygenase 1 (COX-1), also known as prostaglandin-endoperoxide synthase 1 (HUGO PTGS1), is an enzyme that in humans is encoded by the PTGS1 gene. [5] [6] In humans it is one of two cyclooxygenases.
Cyclooxygenases: structural and functional insights
Cyclooxygenase (COX; prostaglandin G/H synthase, EC 1.14.99.1) catalyzes the first two steps in the biosynthesis of prostaglandins (PGs). The two COX isoforms COX-1 and COX-2 are the targets of the widely used nonsteroidal anti-inflammatory drugs, indicating a role for these enzymes in pain, fever, inflammation, and tumorigenesis.
The role of cyclooxygenases in inflammation, cancer, and ...
2000年1月4日 · The cyclooxygenase (COX) enzymes catalyze a key step in the conversion of arachidonate to PGH2, the immediate substrate for a series of cell specific prostaglandin and thromboxane synthases.
