NMR STUDY OF BOVINE HEART FATTY ACID BINDING PROTEINNMR STUDY OF BOVINE HEART FATTY ACID BINDING PROTEIN
Structural highlights
Function[FABPH_BOVIN] FABP are thought to play a role in the intracellular transport of long-chain fatty acids and their acyl-CoA esters. MDGI reversibly inhibits proliferation of mammary carcinoma cells. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe three-dimensional structure of the holo form of recombinant cellular bovine heart fatty-acid-binding protein (H-FABPc), a polypeptide of 133 amino acid residues with a molecular mass of 15 kDa, has been determined by multidimensional homonuclear and heteronuclear NMR spectroscopy applied to uniformly 15N-labeled and unlabeled protein. A nearly complete set of 1H and 15N chemical shift assignments was obtained. A total of 2329 intramolecular distance constraints and 42 side-chain chi 1 dihedral-angle constraints were derived from cross-relaxation and J coupling information. 3D nuclear Overhauser enhancement and exchange spectroscopy combined with heteronuclear multiple-quantum coherence (NOESY-HMQC) experiments, performed on a sample of uniformly 13C-labeled palmitic acid bound to unlabeled cellular heart fatty-acid-binding protein revealed 10 intermolecular contacts that determine the orientation of the bound fatty acid. An ensemble of protein conformations was calculated with the distance-geometry algorithm for NMR applications (DIANA) using the redundant dihedral-angle constraint (REDAC) strategy. After docking the fatty acid into the protein, the protein-ligand arrangement was subject to distance-restrained energy minimization. The overall conformation of the protein is a beta-barrel consisting of 10 antiparallel beta-strands which form two nearly orthogonal beta-sheets of five strands each. Two short helices form a helix-turn-helix motif in the N-terminal region of the polypeptide chain. The palmitic acid is bound within the protein in a U-shaped conformation close to the two helices. The obtained solution structure of the protein is consistent with a number of fatty-acid-binding-protein crystal structures. Three-dimensional structure of bovine heart fatty-acid-binding protein with bound palmitic acid, determined by multidimensional NMR spectroscopy.,Lassen D, Lucke C, Kveder M, Mesgarzadeh A, Schmidt JM, Specht B, Lezius A, Spener F, Ruterjans H Eur J Biochem. 1995 May 15;230(1):266-80.
