STRUCTURE OF RABBIT MUSCLE PYRUVATE KINASE COMPLEXED WITH MN2+, K+, AND PYRUVATE

The structure was published by Larsen, T.M., Laughlin, L.T., Holden, H.M., Rayment, I., and Reed, G.H., in 1994 in a paper entitled "Structure of rabbit muscle pyruvate kinase complexed with Mn2+, K+, and pyruvate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 1994.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of PYRUVATE KINASE. This molecule has the UniProt identifier P11974 (KPYM_RABIT)search. The sample contained 530 residues which is 100% of the natural sequence. Out of 530 residues 513 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.
