The folding of the peptide chain of the bovine heart oxoglutarate carrier in the inner mitochondrial membrane and in the membrane of reconstituted proteoliposomes has been investigated by enzymatic and immunochemical approaches using proteinase K and polyclonal site-directed antibodies, respectively. Two peptides corresponding to the amino acid sequences(More)
Isolated oxoglutarate carrier (OGC) can be cross-linked to dimers by disulfide-forming reagents such as Cu2+-phenanthroline and diamide. Acetone and other solvents increase the extent of Cu2+ -phenanthroline-induced cross-linking of OGC. Cross-linked OGC re-incorporated in proteoliposomes fully retains the oxoglutarate transport activity. The amount of(More)
The Orthogonal Subspace Projection (OSP) algorithm is substantially a kind of matched filter that requires the evaluation of a prototype for each class to be detected. The kernel OSP (KOSP) has recently demonstrated improved results for target detection in hyperspectral images. The use of the kernel method makes the method non-linear, helps to combat the(More)
In this chapter, different approaches to image fusion for pan-sharpening of multispectral images are presented and critically compared. Particular emphasis is devoted to the advantages resulting from defining pan-sharpening as an optimisation problem. Implementation issues are also considered and extensive results in terms of quality of the fused products,(More)
Phosphate and oxoglutarate carriers transport phosphate and oxoglutarate across the inner membranes of mitochondria in exchange for OH- and malate, respectively. Both carriers belong to the mitochondrial carrier protein family, characterized by a tripartite structure made up of related sequences about 100 amino acids in length. The results obtained on the(More)
Two peptides corresponding to the amino acid sequences 1-10 (N-terminal peptide) and 303-313 (C-terminal peptide) of the bovine heart mitochondrial phosphate carrier have been synthesized. After being coupled to ovalbumin, they were injected into rabbits to raise polyclonal antibodies. The specificity of the generated antibodies was tested by enzyme-linked(More)
The interaction of sulfhydryl reagents with the oxoglutarate carrier (OGC) of bovine heart mitochondria was investigated in proteoliposomes reconstituted from purified carrier and lipids. Incubation of the proteoliposomes with maleimides or mercurials led to inhibition of the oxoglutarate carrier protein. The inhibition of oxoglutarate transport by(More)
The dicarboxylate carrier from rat liver mitochondria was purified by the Amberlite/hydroxyapatite procedure and reconstituted in egg yolk phospholipid vesicles by removing the detergent with Amberlite. The efficiency of reconstitution was optimized with respect to the ratio of detergent/phospholipid, the concentration of phospholipid and the number of(More)
