Function[PGH1_SHEEP] May play an important role in regulating or promoting cell proliferation in some normal and neoplastically transformed cells. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedProstaglandin H2 synthase (EC 1.14.99.1) is a clinically important drug target that catalyzes two key steps in the biosynthesis of the eicosanoid hormones. The enzyme contains spatially distinct cyclooxygenase and peroxidase active sites, both of which require a heme cofactor. Substitution of ferric heme by Mn(III) protoporphyrin IX greatly diminishes the peroxidase activity, but has little effect on the cyclooxygenase activity. Here, the 2.0 angstroms resolution crystal structure of the Mn(III) form of ovine prostaglandin H2 synthase-1 is described (R = 21.8%, R(free) = 23.7%). Substitution of Mn(III) for Fe(III) causes no structural perturbations in the protein. However, the out-of-plane displacement of the manganese ion with respect to the porphyrin is greater than that of the iron by approximately 0.2 angstroms. This perturbation may help to explain the altered catalytic properties of the manganese enzyme. 2.0 angstroms structure of prostaglandin H2 synthase-1 reconstituted with a manganese porphyrin cofactor.,Gupta K, Selinsky BS, Loll PJ Acta Crystallogr D Biol Crystallogr. 2006 Feb;62(Pt 2):151-6.
