Quinones 42-50 prostaglandin-endoperoxide synthase 2 Homo sapiens 63-68 19105592-3 2009 We found that human recombinant PGHS-2 catalyzed the oxidation of ortho (2",3"- and 3",4"-) and para (2",5"-) dihydroxy 4-chlorobiphenyl metabolites to their corresponding quinones. Quinones 172-180 prostaglandin-endoperoxide synthase 2 Homo sapiens 32-38
