Identification of Novel Adenine Nucleotide Transporters.

(A) Alignment of amino acid sequences of polypeptides encoded by the TC205692 sequence and Arabidopsis orthologs, At3g05290.1 and At5g27520.1. Areas of gray background show the residues in the solute carrier repeat profile of the mitochondrial carrier family. Asterisks indicate identical amino acid residues, and colons or dots below the alignment denote similar amino acid replacements.

(B) Amino acid sequences encoded by TC205692, At3g05290.1, At5g27520.1, peroxisomal transporters, and Arabidopsis mitochondrial carrier family proteins were compared. The peroxisomal proteins were At PMP38, Hs PMP34, Cb PMP37A, and Sc ANT1p. The Arabidopsis mitochondrial carrier family proteins were At ER-ANT1, At AAC1-3, At FOLT1, At SFC, At UCP1, At DTC, At CAC, At BAC1-2, and At SAMC1/SAMT1. We designated the polypeptide encoded by TC205692, At3g05290.1, and At5g27520.1 as Gm PNC1, At PNC1, and At PNC2, respectively. At NTT1 is used as an outgroup. A text file of the alignment used to generate this tree is available as Supplemental Data Set 1 online.
