Cyclooxygenases: structural, cellular, and molecular biology.
The prostaglandin endoperoxide H synthases-1 and 2 (PGHS-1 and PGHS-2; also cyclooxygenases-1 and 2, COX-1 and COX-2) catalyze the committed step in prostaglandin synthesis. PGHS-1 and 2 are ofExpand

Prostaglandin Endoperoxide H Synthases (Cyclooxygenases)-1 and −2*
Prostaglandin endoperoxide H synthases (PGHSs) catalyze the conversion of arachidonic acid and O2 to PGH2, the committed step in prostanoid biosynthesis (Fig. 1) (1). Before 1991, only one PGHS hadExpand

Differential inhibition of prostaglandin endoperoxide synthase (cyclooxygenase) isozymes by aspirin and other non-steroidal anti-inflammatory drugs.
Murine prostaglandin endoperoxide (PGH) synthase-1 and PGH synthase-2 expressed in cos-1 cells were found to be differentially sensitive to inhibition by common nonsteroidal anti-inflammatory drugsExpand

Prostaglandin endoperoxide H synthases-1 and -2.
Publisher Summary The chapter compares and contrasts the structural and kinetic properties of prostaglandin endoperoxide H synthase-1 (PGHS-1) and -2. It also discusses the description of theExpand

Prostaglandin and thromboxane biosynthesis.
We describe the enzymological regulation of the formation of prostaglandin (PG) D2, PGE2, PGF2 alpha, 9 alpha, 11 beta-PGF2, PGI2 (prostacyclin), and thromboxane (Tx) A2 from arachidonic acid. WeExpand

Differential inhibition of human prostaglandin endoperoxide H synthases-1 and -2 by nonsteroidal anti-inflammatory drugs.
We developed an in vitro expression system for accurate kinetic analyses of the inhibition of the human prostaglandin H synthase isozymes (hPGHS-1 and -2) by nonsteroidal anti-inflammatory drugsExpand

The 19-amino Acid Cassette of Cyclooxygenase-2 Mediates Entry of the Protein into the Endoplasmic Reticulum-associated Degradation System*
Cyclooxygenase (COX) isoforms catalyze the committed step in prostaglandin biosynthesis. The primary structures of COX-1 and COX-2 are very similar except that COX-2 has a 19-amino acid (19-AA)Expand
