XYLOSE ISOMERASE FROM THERMUS CALDOPHILUS

The structure was published by Chang, C., Park, B.C., Lee, D.S., and Suh, S.W., in 1999 in a paper entitled "Crystal structures of thermostable xylose isomerases from Thermus caldophilus and Thermus thermophilus: possible structural determinants of thermostability." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1998.

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

This PDB entry contains multiple copies of the structure of XYLOSE ISOMERASE.
