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
