Parainfluenza Virus 5 (SV5) Hemagglutinin-Neuraminidase (HN) (pH 8.0)

The structure was published by Yuan, P., Thompson, T.B., Wurzburg, B.A., Paterson, R.G., Lamb, R.A., and Jardetzky, T.S., in 2005 in a paper entitled "Structural studies of the parainfluenza virus 5 hemagglutinin-neuraminidase tetramer in complex with its receptor, sialyllactose." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2005.

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

The PDB entry contains the structure of Hemagglutinin-neuraminidase. This molecule has the UniProt identifier P04850 (HN_SV5)search. The sample contained 532 residues which is 94% of the natural sequence. Out of 532 residues 442 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
