This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2007.

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

The PDB entry contains the structure of 3-hydroxyisobutyryl-CoA hydrolase. This molecule has the UniProt identifier Q6NVY1 (HIBCH_HUMAN)search. The sample contained 363 residues which is 92% of the natural sequence. Out of 363 residues 358 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.
