Ferric enterobactin ion 124-130 ferritin heavy chain 1 Homo sapiens 85-96 2065674-8 1991 Analytical and spectroscopic data indicated that fractional rates and equilibria for disassembly of the ferric complex in the presence of apoferritin were independent of the concentration of the protein and of the complex itself. Ferric enterobactin ion 104-110 ferritin heavy chain 1 Homo sapiens 138-149
