title: Kinetic models of cyclooxygenase and peroxidase inactivation of prostaglandin-H-synthase during catalysis.
abstract: Kinetic models of inactivation of cyclooxygenase and peroxidase activities of prostaglandin-H-synthase (PGHS) during cyclooxygenase and peroxidase reactions catalyzed by the enzyme and also on preincubation with H2O2 have been developed; these models account for data obtained by the authors as well as data from the literature. Being rather simple, these models simultaneously describe the processes of cyclooxygenase and peroxidase inactivation of PGHS, using the minimal set of experimental parameters.
