part of nucleotide transmembrane transporter activity FAD transmembrane transporter activity flavin-adenine dinucleotide transmembrane transporter activity FAD carrier activity GO:0015230 flavin adenine dinucleotide carrier activity flavin-adenine dinucleotide carrier activity flavin adenine dinucleotide transmembrane transporter activity GO:0005472 FAD transporter activity Enables the directed movement of flavin-adenine dinucleotide (FAD) from one side of a membrane to the other. FAD forms the coenzyme of the prosthetic group of various flavoprotein oxidoreductase enzymes, in which it functions as an electron acceptor by being reversibly converted to its reduced form. molecular_function FAD transmembrane transport
