The cDNA sequence of proton-pumping nicotinamide nucleotide transhydrogenase from man and mouse.

cDNA clones for the human and mouse nicotinamide nucleotide transhydrogenases have been isolated and their sequences have been determined. Multiple alignments show that the functional proteins are encoded by single mRNAs. The deduced amino acid sequences are approximately 95% identical for the previously known bovine, and the human and mouse proteins. The major variable region is located in the presequence. It is proposed that all mammalian transhydrogenases have a similar structure.
