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 …

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 (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.

The cyclooxygenase isoenzymes, COX-1 and COX-2, catalyze the formation of prostaglandins, thromboxane, and levuloglandins. The prostaglandins are autocoid mediators that affect virtually all known physiological and pathological processes via their reversible interaction with G-protein coupled membra …

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.

2008年10月23日 · 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.

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 …

Characteristics of Cyclooxygenases (COX) or Prostaglandin Synthetases (IUPAC:IUB EC 1.14.99.1). COX -2 and COX-1 thus catalyze the same first committed step of the AA cascade. COX-2, however, is expressed in response to mitogenic and inflammatory stimuli and encoded by an early-response gene.

Cyclooxygenase (COX) is a key enzyme in prostanoid synthesis. It exists in two isoforms, COX-1 and COX-2. COX-1 is referred to as a ‘constitutive isoform’, and is considered to be expressed in most tissues under basal conditions.
