Solution Structure of Recombinant Human Brain-type Fatty acid Binding Protein
Overview
Human brain-type fatty acid-binding protein (B-FABP) has been, recombinantly expressed in Escherichia coli both unlabelled and, 15N-enriched for structure investigation in solution using high-resolution, NMR spectroscopy. The sequential assignments of the 1H and 15N resonances, were achieved by applying multidimensional homo- and heteronuclear NMR, experiments. The ensemble of the 20 final energy-minimized structures, representing human B-FABP in solution, have been calculated based on a, total of 2490 meaningful distance constraints. The overall B-FABP, structure exhibits the typical backbone conformation described for other, members of the FABP family, consisting often antiparallel beta-strands, (betaA to betaJ) that form two almost orthogonal beta-sheets, a, helix-turn-helix motif that closes the beta-barrel on one side, and a, short N-terminal helical loop. A comparison with the crystal structure of, the same protein complexed with docosahexaenoic acid reveals only minor, differences in both secondary structure and overall topology. Moreover, the NMR data indicate a close structural relationship between human B-FABP, and heart-type FABP with respect to fatty acid binding inside the protein, cavity.
