Linoleic Acid Bound to Fatty Acid Binding Protein 4

The structure was published by Gillilan, R.E., Ayers, S.D., and Noy, N., in 2007 in a paper entitled "Structural Basis for Activation of Fatty Acid-binding Protein 4." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2007.

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

The PDB entry contains the structure of Fatty acid-binding protein. This molecule has the UniProt identifier P04117 (FABP4_MOUSE)search. The sample contained 155 residues which is 100% of the natural sequence. Out of 155 residues 130 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
