Human Glutathione Transferase O2 with glutathione -new crystal form

The structure was published by Zhou, H., Brock, J., Liu, D., Board, P.G., and Oakley, A.J., in 2012 in a paper entitled "Structural insights into the dehydroascorbate reductase activity of human omega-class glutathione transferases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2011.

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

The PDB entry contains the structure of Glutathione S-transferase omega-2. This molecule has the UniProt identifier Q9H4Y5 (GSTO2_HUMAN)search. The sample contained 239 residues which is 98% of the natural sequence. Out of 239 residues 238 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 most likely forms homodimers.
