The structure of rat cytosolic PEPCK in complex with oxalate and GTP

The structure was published by Sullivan, S.M. and Holyoak, T., in 2008 in a paper entitled "Enzymes with lid-gated active sites must operate by an induced fit mechanism instead of conformational selection." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.45 Å and deposited in 2008.

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

This PDB entry contains multiple copies of the structure of Phosphoenolpyruvate carboxykinase, cytosolic [GTP].

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.
