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. Enables the transfer of a specific substance or group of related substances from one side of a membrane to the other. Catalysis of the transfer of cation from one side of the membrane to the other. Catalysis of the transfer of amines, including polyamines, from one side of the membrane to the other. Amines are organic compounds that are weakly basic in character and contain an amino (-NH2) or substituted amino group. Catalysis of the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: quaternary ammonium group(out) + H+(out) = quaternary ammonium group(in) + H+(in). Catalysis of the transfer of a specific substance or related group of substances from one side of a membrane to the other, up the solute's concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction. Catalysis of the transfer of organic cations from one side of a membrane to the other. Organic cations are atoms or small molecules with a positive charge that contain carbon in covalent linkage. Catalysis of the transfer of quaternary ammonium groups from one side of a membrane to the other. Quaternary ammonium groups are any compound that can be regarded as derived from ammonium hydroxide or an ammonium salt by replacement of all four hydrogen atoms of the NH4+ ion by organic groups. Enables the directed movement of carnitine into, out of, within or between cells. Carnitine is a compound that participates in the transfer of acyl groups across the inner mitochondrial membrane.
