Catalysis of the transfer of inorganic cations from one side of a membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. Catalysis of the transfer of metal ions from one side of a membrane to the other. Catalysis of the transfer of iron (Fe) ions from one side of a membrane to the other. Catalysis of the transfer of transition metal ions from one side of a membrane to the other. A transition metal is an element whose atom has an incomplete d-subshell of extranuclear electrons, or which gives rise to a cation or cations with an incomplete d-subshell. Transition metals often have more than one valency state. Biologically relevant transition metals include vanadium, manganese, iron, copper, cobalt, nickel, molybdenum and silver. Catalysis of the transfer of ferrous iron (Fe(II) or Fe2+) ions from one side of a membrane to the other. Catalysis of the transfer of inorganic cations with a valency of two or three from one side of the membrane to the other. Inorganic cations are atoms or small molecules with a positive charge that do not contain carbon in covalent linkage. Catalysis of the transfer of an iron chelate from one side of a membrane to the other. An iron chelate is a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions. Catalysis of the transfer of ferric iron (Fe(III) or Fe3+) ions from one side of a membrane to the other. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: siderophore-iron(out) + H+(out) = siderophore-iron(in) + H+(in). Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Fe2+(out) = Fe2+(in).
