1. Superexpression of the ADP/ATP Translocase in Maize Under Saline and Aluminum Stresses / SuperexpressÃo do ADP/ATP translocase em milho submetido aos estresses salino e de alumÃnio
The Brazilian Cerrado occupies an area with about 207 million hectares distributed in 12 states In this region the soils are acid with little organic substance and high aluminum levels Under the form of free ions the aluminum becomes toxic for the plants and affects their growth and development Maize considered an important culture in these areas suffers sev

2. Two distinct genes for ADP/ATP translocase are expressed at the mRNA level in adult human liver.
Several clones hybridizing with a bovine ADP/ATP translocase cDNA were isolated from an adult human liver cDNA library in the vector pEX1. DNA sequence analysis revealed that these clones encode two distinct forms of translocase. In particular, two clones specifying the COOH-end-proximal five-sixths of the protein exhibit a 9% amino acid sequence divergence

3. Identification and initial topological analysis of the Rickettsia prowazekii ATP/ADP translocase.
The Rickettsia prowazekii ATP/ADP translocase was identified by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE) and immunoblot analysis using antibodies raised against a synthetic peptide corresponding in sequence to the carboxyl-terminal 17 amino acids of the carrier. Both the translocase of R. prowazekii and that expressed by Escheri

4. Sequence of the bovine mitochondrial phosphate carrier protein: structural relationship to ADP/ATP translocase and the brown fat mitochondria uncoupling protein.
A cDNA encoding the precursor of the bovine mitochondrial phosphate carrier protein has been cloned from a bovine cDNA library using a mixture of 128 different 17-mer oligonucleotides as hybridisation probe. The protein has an N-terminal extension of 49 amino acids not present in the mature protein. This extension has a net positive charge and is presumed to

6. Evidence for adenylate nucleotide transport (ATP-ADP translocation) in vesicles of Frankia sp. strain EAN1pec.
Atractyloside and carboxyatractyloside partially inhibited nitrogenase activity (acetylene reduction) by isolated vesicles of Frankia strain EAN1pec. Extracts of disrupted vesicles showed nitrogenase activity that was not affected by the inhibitors. The vesicles accumulated ATP by an atractyloside-sensitive mechanism. This inhibition of ATP uptake was revers

7. 31P NMR magnetization transfer study of the control of ATP turnover in Saccharomyces cerevisiae.
31P NMR magnetization transfer measurements have been used to measure the steady state flux between Pi and ATP in yeast cells genetically modified to overexpress an adenine nucleotide translocase isoform. An increase in Pi -> ATP flux and apparent ratio of moles of ATP synthesized/atoms of oxygen consumed (P:O ratio), when these cells were incubated with glu

8. Energy-linked Adenosine Diphosphate Accumulation by Corn Mitochondria: I. General Characteristics and Effect of Inhibitors 1
Corn mitochondria show respiration-linked net accumulation of [3H]ADP in the presence of phosphate and magnesium, especially if the formation of ATP is blocked with oligomycin. Inhibition of ADP-ATP exchange by carboxyatractyloside also activates ADP accumulation, and addition of carboxyatractyloside or palmitoyl-coenzyme A to oligomycin-blocked mitochondria

9. Participation of N1-Oxide derivatives of Adenine Nucleotides in the Phosphotransferase Activity of Liver Mitochondria
The modified adenine nucleotides ATP-NO, ADP-NO, and AMP-NO were tested as potential substrates and/or inhibitors of mitochondrial phosphotransferases. ADP-NO is not recognized by the translocase system located in the inner mitochondrial membrane; however, it is rapidly phosphorylated to ATP-NO in the outer compartment of mitochondria, by way of the nucleosi

10. History of the ADP/ATP-Translocase-Encoding Gene, a Parasitism Gene Transferred from a Chlamydiales Ancestor to Plants 1 Billion Years Ago
Nonmitochondrial ADP/ATP translocase is an energy parasite enzyme. Its encoding gene, tlc, is found only in Rickettsiales, Chlamydiales, and plant and alga plastids. We demonstrate the presence of tlc in Parachlamydia acanthamoebae. This gene shares more similarity with the tlc1 gene of Chlamydiaceae and the tlc of plant and alga plastids than with the tlc2

11. ATP/ADP Translocases: a Common Feature of Obligate Intracellular Amoebal Symbionts Related to Chlamydiae and Rickettsiae
ATP/ADP translocases catalyze the highly specific transport of ATP across a membrane in an exchange mode with ADP. Such unique transport proteins are employed by plant plastids and have among the prokaryotes so far only been identified in few obligate intracellular bacteria belonging to the Chlamydiales and the Rickettsiales. In this study, 12 phylogenetical

12. The Nucleotide Transporter of Caedibacter caryophilus Exhibits an Extended Substrate Spectrum Compared to the Analogous ATP/ADP Translocase of Rickettsia prowazekii
The two obligate intracellular alphaproteobacteria Rickettsia prowazekii and Caedibacter caryophilus, a human pathogen and a paramecium endosymbiont, respectively, possess transport systems to facilitate ATP uptake from the host cell cytosol. These transport proteins, which have 65% identity at the amino acid level, were heterologously expressed in Escherich
