==THE THREE-DIMENSIONAL STRUCTURE OF ACYL-COENZYME A BINDING PROTEIN FROM BOVINE LIVER. STRUCTURAL REFINEMENT USING HETERONUCLEAR MULTIDIMENSIONAL NMR SPECTROSCOPY==
The 3D structure of bovine recombinant acyl-coenzyme A binding protein has, been determined using multidimensional heteronuclear magnetic resonance, spectroscopy in a study that combines investigations of 15N-labeled and, unlabeled protein. The present structure determination is a refinement of, the structure previously determined (Andersen, K.V. and Poulsen, F.M., (1992) J. Mol. Biol., 226, 1131-1141). It is based on 1096 distance, restraints and 124 dihedral angle restraints of which 69 are for, phi-angles and 8 for chiral centers and 47 for prochiral centers. The new, experimental input for the structure determination has provided an, increase of 263 distance restraints, 5 phi-angle restraints, and 32, chi-angle restraints in 2 chiral centers, and 31 prochiral centers, restraining an additional 23 chi 1, 8 chi 2, and 1 chi 3 angles. The, increase of 300 distance and dihedral angle restraints representing an, additional 30% of input parameters for the structure determination has, been shown to be in agreement with the first structure. A set of 29, structures has been calculated and each of the structures has been, compared to a mean structure to give an atomic root mean square deviation, of 0.44 +/- 0.12 A (1 A is 0.1 nm) for the backbone atoms C, C alpha, and, N in the four alpha-helices A1, residues 4-15, A2, residues 21-36, A3, residues 51-62 and A4, residues 65-84. The loop-region of residues, Gly45-Lys50 could not be defined by the restraints obtained by NMR. The, program PRONTO has been used for the spectrum analysis, assignment of the, individual nuclear Overhauser effects, the integration of the cross peaks, and the measurement of the coupling constants. The programs DIANA, X-PLOR, and INSIGHT have been used in the structure calculations and evaluations.

Structural highlights

2abd is a 1 chain structure with sequence from Bos taurus. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:Solution NMR
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

ACBP_BOVIN Binds medium- and long-chain acyl-CoA esters with very high affinity and may function as an intracellular carrier of acyl-CoA esters. It is also able to displace diazepam from the benzodiazepine (BZD) recognition site located on the GABA type A receptor. It is therefore possible that this protein also acts as a neuropeptide to modulate the action of the GABA receptor.[1]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
