The reactions of native prostaglandin endoperoxide synthase with structurally different hydroperoxides have been investigated by using kinetic spectrophotometric scan and conventional and sequential mixing stopped-flow experiments. The second order rate constants for compound I formation are (5.9 +/- 0.1) x

Under aerobic conditions, exposure of peroxidized lipids to nitric oxide (NO) was found to result in a rapid decrease in the levels of thiobarbituric acid-reactive substances (TBARS). Addition of 10-100 microM NO to rat brain homogenates preincubated for 2 h

Prostaglandin H synthase (PGHS) is a heme protein that catalyzes both the cyclooxygenase and peroxidase reactions needed to produce prostaglandins G2 and H2 from arachidonic acid. Replacement of the heme group by mangano protoporphyrin IX largely preserves the cyclooxygenase activity

Arachidonic acid is converted to prostaglandin G(2) (PGG(2)) by the cyclooxygenase activities of prostaglandin endoperoxide H synthases (PGHSs) 1 and 2. The initial, rate-limiting step is abstraction of the 13-proS hydrogen from arachidonate which, for PGG(2) formation, is followed by
The Journal of biological chemistry, 266(19), 12348-12355 (1991-07-05)
Prostaglandin H synthase oxidizes arachidonic acid to prostaglandin G2 (PGG2) via its cyclooxygenase activity and reduces PGG2 to prostaglandin H2 by its peroxidase activity. The purpose of this study was to determine if endogenously generated PGG2 is the preferred substrate
