Crystal structure of Streptococcus pneumoniae D39 neuraminidase A precursor (NanA)

The structure was published by Hsiao, Y.-S., Parker, D., Ratner, A.J., Prince, A., and Tong, L., in 2009 in a paper entitled "Crystal structures of respiratory pathogen neuraminidases" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2009.

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

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

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