M., Takahashi, S., Fujii, H., Zhou, H., Ishikawa, K., Yoshimura, T., Rousseau, D. L., Yoshida, T., and Ikeda-Saito, M. (1996) J. Biol. verdoheme 130-139 heme oxygenase 1 Homo sapiens 110-126 15606196-6 2004 Exposure of the one-electron- or two-electron-reduced verdoheme complexes of cytochrome b(5) to O(2) results in rapid and quantitative reoxidation to the resting state [Fe(II)(verdoheme)](+) complex. verdoheme 54-63 mitochondrially encoded cytochrome b Homo sapiens 77-89 15606196-6 2004 Exposure of the one-electron- or two-electron-reduced verdoheme complexes of cytochrome b(5) to O(2) results in rapid and quantitative reoxidation to the resting state [Fe(II)(verdoheme)](+) complex. verdoheme 176-185 mitochondrially encoded cytochrome b Homo sapiens 77-89 12809497-5 2003 Heme oxygenase-1 converted all four isomers of meso-hydroxyhemin to the corresponding isomers of verdoheme. verdoheme 97-106 heme oxygenase 1 Rattus norvegicus 0-16 10373419-11 1999 The verdoheme formed from alpha-hydroxyheme was shown to be in the ferrous oxidation state by the addition of CO or potassium ferricyanide to the resultant verdoheme-heme oxygenase-1 complex. verdoheme 4-13 heme oxygenase 1 Homo sapiens 166-182 7890772-7 1995 The reaction with hydrogen peroxide converted the heme of the heme oxygenase-2 fragment complex into a verdoheme-like intermediate, while the reaction with m-chloroperbenzoic acid yielded a oxoferryl species. verdoheme 103-112 heme oxygenase 2 Homo sapiens 62-78
