CYCLOOXYGENASE COMPETITIVE INHIBITORS ALTER TYROSYL RADICAL DYNAMICS IN PROSTAGLANDIN H SYNTHASE-2

Reaction of prostaglandin H synthase (PGHS) isoforms 1 or 2 with peroxide forms a radical at Tyr385 that is required for cyclooxygenase catalysis, and another radical at Tyr504, whose function is unknown. Both tyrosyl radicals are transient and rapidly dissipated by reductants, suggesting that cyclo...
