Crystal Structure Of Xylanase From Streptomyces Olivaceoviridis E-86 Complexed With 2(2)-alpha-L-arabinofuranosyl-xylobiose

The structure was published by Fujimoto, Z., Kaneko, S., Kuno, A., Kobayashi, H., Kusakabe, I., and Mizuno, H., in 2004 in a paper entitled "Crystal structures of decorated xylooligosaccharides bound to a family 10 xylanase from Streptomyces olivaceoviridis E-86" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of endo-1,4-beta-D-xylanase.

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 homodimers.
