Crystal structure of human glutathione transferase (GST) A1-1 in complex with glutathione

The structure was published by Grahn, E., Novotny, M., Jakobsson, E., et al., Wahlberg, M., Mannervik, B., and Kleywegt, G.J., in 2006 in a paper entitled "New crystal structures of human glutathione transferase A1-1 shed light on glutathione binding and the conformation of the C-terminal helix." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of Glutathione S-transferase A1.

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.
