1khe Summary


PEPCK complex with nonhydrolyzable GTP analog, MAD data

The structure was published by Dunten, P., Belunis, C., Crowther, R., et al., Swain, A., Weber, D., and Wertheimer, S.J., in 2002 in a paper entitled "Crystal structure of human cytosolic phosphoenolpyruvate carboxykinase reveals a new GTP-binding site." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2001.

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

The PDB entry contains the structure of Phosphoenolpyruvate Carboxykinase, cytosolic (GTP). This molecule has the UniProt identifier P35558 (PCKGC_HUMAN)search. The sample contained 625 residues which is 100% of the natural sequence. Out of 625 residues 602 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.
