Lipid Peroxides 207-227 prostaglandin-endoperoxide synthase 1 Homo sapiens 140-156 17209563-5 2007 The kinetics of tyrosyl radical, oxyferryl heme, and peroxidase inactivation were examined in reactions of PGHS-1 reconstituted with heme or mangano protoporphyrin IX with a lipid hydroperoxide, 15-hydroperoxyeicosatetraenoic acid (15-HPETE), and ethyl hydrogen peroxide (EtOOH). Lipid Peroxides 174-193 prostaglandin-endoperoxide synthase 1 Homo sapiens 107-113 10347169-5 1999 With 15-hydroperoxyeicosatetraenoic acid, the rate constant for Intermediate I formation (k1) was 2.3 x 10(7) M-1 s-1 for PGHS-1 and 2.5 x 10(7) M-1 s-1 for PGHS-2, indicating that the isoforms have similar initial reactivity with this lipid hydroperoxide. Lipid Peroxides 236-255 prostaglandin-endoperoxide synthase 1 Homo sapiens 122-134 10993875-4 2000 With purified ovine PGHS-1, ( small middle dot)NO consumption requires peroxide (LOOH or H(2)O(2)), with a K(m)( (app)) for 15(S)hydroperoxyeicosatetraenoic acid (HPETE) of 3.
