Structure of bovine Acyl-CoA binding protein in orthorhombic crystal form
Structural highlights
FunctionACBP_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.

Publication Abstract from PubMedAcyl-CoA binding protein (ACBP) maintains a pool of fatty acyl-CoA molecules in the cell and plays a role in fatty acid metabolism. The biochemical properties of Plasmodium falciparum ACBP are described together with the 2.0 A resolution crystal structures of a P. falciparum ACBP-acyl-CoA complex and of bovine ACBP in two crystal forms. Overall, the bovine ACBP crystal structures are similar to the NMR structures published previously; however, the bovine and parasite ACBP structures are less similar. The parasite ACBP is shown to have a different ligand-binding pocket, leading to an acyl-CoA binding specificity different from that of bovine ACBP. Several non-conservative differences in residues that interact with the ligand were identified between the mammalian and parasite ACBPs. These, together with measured binding-specificity differences, suggest that there is a potential for the design of molecules that might selectively block the acyl-CoA binding site.
