Sulfites 95-102 mitochondrially encoded cytochrome c oxidase II Homo sapiens 68-74 1645541-1 1991 Exposure of albumin to sulfite in the presence of Co(II) or peroxidase/H2O2 caused site-specific fragmentation, which was not due to cleavage of methionyl nor tryptophanyl peptide bonds. Sulfites 23-30 mitochondrially encoded cytochrome c oxidase II Homo sapiens 50-56 1645541-2 1991 The reaction of GlyPro with sulfite in the presence of Co(II) or peroxidase/H2O2 led to Gly liberation, suggesting the oxidative cleavage of protein at Pro residues. Sulfites 28-35 mitochondrially encoded cytochrome c oxidase II Homo sapiens 55-61 1645541-4 1991 ESR-spin trapping method provided evidence for the formation of sulfate radical (SO4.-) during Co(II)-catalyzed autoxidation of sulfite. Sulfites 128-135 mitochondrially encoded cytochrome c oxidase II Homo sapiens 95-101 31240657-7 2019 Overall, activation of sulfite to produce reactive radicals with extremely low Co(II) or Cu(II) concentrations (in the range of mug L-1) in circumneutral conditions is confirmed, which offers a potential SO4 --based advanced oxidation process in treatment of aquatic organic contaminants. Sulfites 23-30 mitochondrially encoded cytochrome c oxidase II Homo sapiens 79-85 23999614-2 2013 We found that the two Co(I) species were oxidized by these sulfur-containing compounds to Co(II) forms: oxidation by excess thiosulfate leads to penta-coordinate complexes and oxidation by excess sulfite or dithionite leads to hexa-coordinate Co(II)-SO2(-) complexes. Sulfites 196-203 mitochondrially encoded cytochrome c oxidase II Homo sapiens 90-96 18854902-2 2008 These studies indicated that only Co(II) complexed with glycylglycylhistidine (GGH) induced DNA strand breaks at low sulfite concentrations (1-80 microM) via strong oxidants formed in the reaction. Sulfites 117-124 mitochondrially encoded cytochrome c oxidase II Homo sapiens 34-40 18854902-3 2008 In the presence of the other complexes, some damage occurred only in the presence of high sulfite concentrations (0.1-2.0 mM) after incubation for 4 h. In the presence of GGH, Co(II) and dissolved O2, DNA damage must involve a reactive high-valent cobalt complex. Sulfites 90-97 mitochondrially encoded cytochrome c oxidase II Homo sapiens 176-182 23244055-7 2013 The results suggest that sulfite is rapidly autoxidized in the presence of Co(II), Cu(II), Cr(VI), Fe(III), and Mn(II), producing radicals that cause the DNA damage. Sulfites 25-32 mitochondrially encoded cytochrome c oxidase II Homo sapiens 75-81 23244055-8 2013 These radicals can be ranked in a descending order of their ability to induce DNA damage with sulfite as follows: Fe(III) > Co(II) > Cu(II) > Cr(VI) > Mn(II).
