ATOMIC RESOLUTION STRUCTURE OF THE BACTERIAL SIALIDASE NANI FROM CLOSTRIDIUM PERFRINGENS IN COMPLEX WITH ALPHA-SIALIC ACID (NEU5AC).

The structure was published by Newstead, S.L., Potter, J.A., Wilson, J.C., et al., Watts, A.G., Withers, S.G., and Taylor, G.L., in 2008 in a paper entitled "The Structure of Clostridium Perfringens Nani Sialidase and its Catalytic Intermediates." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 0.97 Å and deposited in 2004.

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

The PDB entry contains the structure of EXO-ALPHA-SIALIDASE. This molecule has the UniProt identifier Q59310 (Q59310_CLOPF)search. The sample contained 449 residues which is < 90% of the natural sequence. Out of 449 residues 448 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.
