Abstract
The synthesis of DNA in mitochondria requires the uptake of deoxynucleotides into the matrix of the organelle. We have characterized a human cDNA encoding a member of the family of mitochondrial carriers. The protein has been overexpressed in bacteria and reconstituted into phospholipid vesicles where it catalyzed the transport of all four deoxy (d) NDPs, and, less efficiently, the corresponding dNTPs, in exchange for dNDPs, ADP, or ATP. It did...
