LDMN is a syndrome characterized by leukoencephalopathy, dystonic head tremor, spasmodic torticollis and reduced tendon reflexes in lower extremities. Additional features include hyposmia, pathologic saccadic eye movements, a slight hypoacusis, accumulation of branched-chain pristanic acid in plasma, and the presence of abnormal bile alcohol glucuronides in urine.<ref>PMID:16685654</ref> | ||

| + | The determination of the NMR structure of the sterol carrier protein-2 (SCP2), analysis of backbone (15)N spin relaxation parameters and NMR studies of nitroxide spin-labeled substrate binding are presented as a new basis for investigations of the mode of action of SCP2. The SCP2 fold is formed by a five-stranded beta-sheet and four alpha-helices. Fatty acid binding to a hydrophobic surface area formed by amino acid residues of the first and third helices, and the beta-sheet, which are all located in the polypeptide segment 8-102, was identified with the use of the spin-labeled substrate 16-doxylstearic acid. In the free protein, the lipid-binding site is covered by the C-terminal segment 105-123, suggesting that this polypeptide segment, which carries the peroxisomal targeting signal (PTS1), might be involved in the regulation of ligand binding. | ||
