The mitochondrial ADP/ATP carrier in Saccharomyces cerevisiae is encoded by three genes that are differentially expressed under different physiological conditions. We investigated the transcriptional control of AAC3, an oxygen-repressed isoform. By deletion analysis, DNA electrophoretic mobility-shift assays, DNase I footprinting and site-directed mutagenesis, we have identified a promoter regi...
Blue native gel electrophoresis is a popular method for the determination of the oligomeric state of membrane proteins. Studies using this technique have reported that mitochondrial carriers are dimeric (composed of two ∼32-kDa monomers) and, in some cases, can form physiologically relevant associations with other proteins. Here, we have scrutinized the behavior of the yeast mitochondrial ADP/A...
The KlAAC gene, encoding the ADP/ATP carrier, has been assumed to be a single gene in Kluyveromyces lactis, an aerobic, petite-negative yeast species. The Klaac null mutation, which causes a respiratory-deficient phenotype, was fully complemented by AAC2, the Saccharomyces cerevisiae major gene for the ADP/ATP carrier and also by AAC1, a gene that is poorly expressed in S. cerevisiae. In this s...
The ADP/ATP carrier protein (AAC) expressed in Artemia franciscana is refractory to bongkrekate. We generated two strains of Saccharomyces cerevisiae where AAC1 and AAC3 were inactivated and the AAC2 isoform was replaced with Artemia AAC containing a hemagglutinin tag (ArAAC-HA). In one of the strains the suppressor of ΔAAC2 lethality, SAL1, was also inactivated but a plasmid coding for yeast A...
AAC2 is one of three paralogs encoding mitochondrial ADP/ATP carriers in the yeast Saccharomyces cerevisiae, and because it is required for respiratory growth it has been the most extensively studied. To comparatively examine the relative functionality of Aac1, Aac2, and Aac3 in vivo, the gene encoding each isoform was expressed from the native AAC2 locus in aac1Delta aac3Delta yeast. Compared ...
