Sulfites 114-121 cytochrome c, somatic Homo sapiens 55-67 14729666-3 2004 In steady-state assays of Y343F sulfite oxidase using cytochrome c as the electron acceptor, k(cat) was somewhat impaired ( approximately 34% wild-type activity at pH 8.5), whereas the K(m)(sulfite) showed a 5-fold increase over wild type. Sulfites 32-39 cytochrome c, somatic Homo sapiens 54-66 24793416-7 2014 Sulfite also induced mitochondrial swelling and reduced mitochondrial membrane potential, Ca(2+) retention capacity, NAD(P)H pool and cytochrome c immunocontent when Ca(2+) was present in the medium. Sulfites 0-7 cytochrome c, somatic Homo sapiens 134-146 17009250-5 2006 After copper is added to the sulfite-cytochrome c binary systems, the reaction between sulfite and the protein component in cytochrome c is obviously strengthened at a low concentration (K(A) = 7.289 L mol(-1)), while the addition of copper merely has a little effect on the interaction between sulfite and the ferroporphyrin component in cytochrome c. Sulfites 29-36 cytochrome c, somatic Homo sapiens 37-49 17009250-5 2006 After copper is added to the sulfite-cytochrome c binary systems, the reaction between sulfite and the protein component in cytochrome c is obviously strengthened at a low concentration (K(A) = 7.289 L mol(-1)), while the addition of copper merely has a little effect on the interaction between sulfite and the ferroporphyrin component in cytochrome c. Sulfites 29-36 cytochrome c, somatic Homo sapiens 124-136 17009250-5 2006 After copper is added to the sulfite-cytochrome c binary systems, the reaction between sulfite and the protein component in cytochrome c is obviously strengthened at a low concentration (K(A) = 7.289 L mol(-1)), while the addition of copper merely has a little effect on the interaction between sulfite and the ferroporphyrin component in cytochrome c.

Sulfites 87-94 cytochrome c, somatic Homo sapiens 37-49 17009250-5 2006 After copper is added to the sulfite-cytochrome c binary systems, the reaction between sulfite and the protein component in cytochrome c is obviously strengthened at a low concentration (K(A) = 7.289 L mol(-1)), while the addition of copper merely has a little effect on the interaction between sulfite and the ferroporphyrin component in cytochrome c. Sulfites 87-94 cytochrome c, somatic Homo sapiens 124-136 17009250-5 2006 After copper is added to the sulfite-cytochrome c binary systems, the reaction between sulfite and the protein component in cytochrome c is obviously strengthened at a low concentration (K(A) = 7.289 L mol(-1)), while the addition of copper merely has a little effect on the interaction between sulfite and the ferroporphyrin component in cytochrome c. Sulfites 87-94 cytochrome c, somatic Homo sapiens 124-136 26709389-9 2016 Studies were performed to understand the related mechanism of oxidation of sulfite and radical generation by ferric cytochrome c (Fe3+ cyt c) in the absence and presence of H2O2. Sulfites 75-82 cytochrome c, somatic Homo sapiens 116-128 26709389-9 2016 Studies were performed to understand the related mechanism of oxidation of sulfite and radical generation by ferric cytochrome c (Fe3+ cyt c) in the absence and presence of H2O2. Sulfites 75-82 cytochrome c, somatic Homo sapiens 135-140 26709389-12 2016 The amount of DMPO-SO3- formed from the oxidation of sulfite by the Fe3+ cyt c increased with sulfite concentration. Sulfites 53-60 cytochrome c, somatic Homo sapiens 73-78 26709389-12 2016 The amount of DMPO-SO3- formed from the oxidation of sulfite by the Fe3+ cyt c increased with sulfite concentration. Sulfites 94-101 cytochrome c, somatic Homo sapiens 73-78 26709389-13 2016 In addition, the amount of DMPO-SO3- formed by the peroxidase activity of Fe3+ cyt c also increased with sulfite and H2O2 concentration. Sulfites 105-112 cytochrome c, somatic Homo sapiens 79-84 26709389-14 2016 From these results, we propose a mechanism in which the Fe3+ cyt c and its peroxidase activity oxidizes sulfite to sulfite radical. Sulfites 104-111 cytochrome c, somatic Homo sapiens 61-66 26709389-15 2016 Our results suggest that Fe3+ cyt c could have a novel role in the deleterious effects of sulfite in biological systems due to increased production of sulfite radical.
