Comments
Comment typeDescription
Biophysicochemical PropertiesKinetic parameters: KM=83 uM for ATP {ECO:0000269|PubMed:19073763};
Developmental StageExpressed in the early seedling stage of post-germinative growth. {ECO:0000269|PubMed:19073762}.
FunctionPeroxisomal adenine nucleotide transporter catalyzing the counterexchange of ATP with AMP. ATP is needed by reactions that generate acyl-CoA for peroxisomal fatty acid beta-oxidation during postgerminative growth. Required for the beta-oxidation reactions involved in auxin biosynthesis and for the conversion of seed-reserved triacylglycerols into sucrose that is necessary for growth before the onset of photosynthesis. {ECO:0000269|PubMed:19073762, ECO:0000269|PubMed:19073763}.
SimilarityBelongs to the mitochondrial carrier (TC 2.A.29) family. {ECO:0000305}.
SimilarityContains 3 Solcar repeats. {ECO:0000255|PROSITE- ProRule:PRU00282}.
Subcellular LocationPeroxisome membrane {ECO:0000269|PubMed:19073762, ECO:0000269|PubMed:19073763}; Multi- pass membrane protein {ECO:0000269|PubMed:19073762, ECO:0000269|PubMed:19073763}.
Tissue SpecificityExpressed in stamens, pollen grains, seeds, leaves, cotyledons, roots, stems, flowers, hypocotyls and siliques. {ECO:0000269|PubMed:19073763}.
