SUGAR RING DISTORTION IN THE GLYCOSYL-ENZYME INTERMEDIATE OF A FAMILY G/11 XYLANASE

The structure was published by Sidhu, G., Withers, S.G., Nguyen, N.T., McIntosh, L.P., Ziser, L., and Brayer, G.D., in 1999 in a paper entitled "Sugar ring distortion in the glycosyl-enzyme intermediate of a family G/11 xylanase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1998.

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

The PDB entry contains the structure of ENDO-1,4-BETA-XYLANASE. This molecule has the UniProt identifier P09850 (XYNA_BACCI)search. The sample contained 185 residues which is 100% of the natural sequence. Out of 185 residues 185 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.
