Catalysis of the transfer of purines, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, from one side of a membrane to the other. Catalysis of the transfer of a nucleobase, any nitrogenous base that is a constituent of a nucleoside, nucleotide, or nucleic acidfrom one side of a membrane to the other. Catalysis of the transfer of xanthine from one side of a membrane to the other. Xanthine (2,6-dihydroxypurine) is a purine formed in the metabolic breakdown of guanine, but is not present in nucleic acids.
