Ferric enterobactin ion 17-23 insulin like growth factor 1 Homo sapiens 181-187 9294820-9 1997 The covalent dimerization of hIGF-I was correlated to visible light and ferric ions. Ferric enterobactin ion 72-78 insulin like growth factor 1 Homo sapiens 29-35 9294820-12 1997 The oxidation of methionine 59 in hIGF-I is catalyzed by light and by ferric ions in combination with EDTA. Ferric enterobactin ion 70-76 insulin like growth factor 1 Homo sapiens 34-40 9294820-13 1997 The covalent dimerization of hIGF-I is mainly affected by light and by ferric ions. Ferric enterobactin ion 71-77 insulin like growth factor 1 Homo sapiens 29-35 9294820-16 1997 EDTA is necessary for ferric ions to be active in the oxidation of methionine in hIGF-I but not for the covalent dimerization. Ferric enterobactin ion 22-28 insulin like growth factor 1 Homo sapiens 81-87
