Isolation and properties of enzymes involved in prostaglandin biosynthesis.


Prostaglandin (PG) endoperoxide synthetase was purified until homogeneity had been attained. The pure enzyme displays both cyclooxygenase and peroxidase activity, in accordance with the work of MIYAMOTO et al. (J. biol. Chem. 252, 2629--2636 (1976)). This enzyme therefore converts arachidonic acid into PGH2. Glutathione S-transferases, in the presence of… (More)
