Crystal structure of human adipocyte fatty acid binding protein in complex with a carboxylic acid ligand

The structure was published by Lehmann, F., Haile, S., Axen, E., et al., Lundback, T., Rondahl, L., and Barf, T., in 2004 in a paper entitled "Discovery of inhibitors of human adipocyte fatty acid-binding protein, a potential type 2 diabetes target." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2004.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of Fatty acid-binding protein, adipocyte. This molecule has the UniProt identifier P15090 (FABP4_HUMAN)search. The sample contained 131 residues which is 99% of the natural sequence. Out of 131 residues 131 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
