1w0o Summary



The structure was published by Moustafa, I., Connaris, H., Taylor, M., et al., Kiefel, J.C.Wilsonm.J., Von-Itzstein, M., and Taylor, G., in 2004 in a paper entitled "Sialic Acid Recognition by Vibrio Cholerae Neuraminidase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2004.

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

The PDB entry contains the structure of SIALIDASE. This molecule has the UniProt identifier P0C6E9 (NANH_VIBCH)search. The sample contained 781 residues which is < 90% of the natural sequence. Out of 781 residues 753 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.
