STRUCTURE OF THE CATALYTIC DOMAIN OF THE NATIVE NANA SIALIDASE FROM STREPTOCOCCUS PNEUMONIAE

The structure was published by Xu, G., Li, X., Andrew, P.W., and Taylor, G.L., in 2008 in a paper entitled "Structure of the Catalytic Domain of Streptococcus Pneumoniae Sialidase Nana." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.49 Å and deposited in 2008.

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

This PDB entry contains multiple copies of the structure of SIALIDASE A.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
