Escherichia coli ketopantoate reductase in complex with 2-monophosphoadenosine-5'-diphosphate

The structure was published by Ciulli, A., Lobley, C.M., Tuck, K.L., Smith, A.G., Blundell, T.L., and Abell, C., in 2007 in a paper entitled "pH-tuneable binding of 2'-phospho-ADP-ribose to ketopantoate reductase: a structural and calorimetric study." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.95 Å and deposited in 2005.

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

The PDB entry contains the structure of 2-dehydropantoate 2-reductase. This molecule has the UniProt identifier P0A9J4 (PANE_ECOLI)search. The sample contained 303 residues which is 100% of the natural sequence. Out of 303 residues 291 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.
