This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 2005.

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

The PDB entry contains the structure of Sialidase 2. This molecule has the UniProt identifier Q9Y3R4 (NEUR2_HUMAN)search. The sample contained 382 residues which is 100% of the natural sequence. Out of 382 residues 356 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.
