    3.5.1.102 | Fe2+ |
addition of more than 1 mM Fe2+ increases the rate of 2,5-diamino-6-ribosylamino-4(3H)-pyrimidinone 5'-phosphate production by more than 10fold, purified enzyme contains both 1.4 mol iron and 6.2 mol magnesium per mol of protomer, maximum activity of Chelex-treated enzyme with added Fe2+ is 30% that of the untreated enzyme indicating that the apoenzyme cannot be fully reconstituted with the addition of just one metal |

| 3.5.1.102 | Mg2+ |
enzyme contains both 1.4 mol Fe2+ and 6.2 mol Mg2+ per mol of protomer |

| 3.5.1.102 | Mn2+ |
addition of more than 1 mM Mn2+ increases the rate of 2,5-diamino-6-ribosylamino-4(3H)-pyrimidinone 5'-phosphate production by more than 10fold, maximum activity of Chelex-treated enzyme with added Mn2+ is 30% that of the untreated enzyme indicating that the apoenzyme cannot be fully reconstituted with the addition of just one metal |

| 3.5.1.102 | Zn2+ |
zinc is associated with the purified protein, 1.5 mol/protomer, despite the presence of zinc in the protein, addition of Zn(II) to the incubation mixture containing purified enzyme or apo-enzyme does not activate ArfB |
