Influenza virus neuraminidase subtype N9 (TERN) complexed with 2,3-dif guanidino-neu5ac2en inhibitor

The structure was published by Kim, J.-H., Resende, R., Wennekes, T., et al., McKimm-Breschkin, J.L., Niikura, M., and Withers, S.G., in 2013 in a paper entitled "Mechanism-based covalent neuraminidase inhibitors with broad-spectrum influenza antiviral activity" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2012.

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

The PDB entry contains the structure of Neuraminidase. This molecule has the UniProt identifier P03472 (NRAM_I75A5)search. The sample contained 388 residues which is < 90% of the natural sequence. Out of 388 residues 388 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 most likely forms homotetramers.
