High-resolution study of D-Xylose isomerase, 0.94A resolution.

The structure was published by Katz, A.K., Li, X., Carrell, H.L., et al., Schoenborn, B.P., Glusker, J.P., and Bunick, G.J., in 2006 in a paper entitled "Locating active-site hydrogen atoms in D-xylose isomerase: Time-of-flight neutron diffraction." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 0.94 Å and deposited in 2006.

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

The PDB entry contains the structure of Xylose isomerase. This molecule has the UniProt identifier P24300 (XYLA_STRRU)search. The sample contained 388 residues which is 100% of the natural sequence. Out of 388 residues 388 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 most likely forms homotetramers.
