1ivb Summary



The structure was published by Jedrzejas, M.J., Singh, S., Brouillette, W.J., Laver, W.G., Air, G.M., and Luo, M., in 1995 in a paper entitled "Structures of aromatic inhibitors of influenza virus neuraminidase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 1994.

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

The PDB entry contains the structure of INFLUENZA VIRUS B/LEE/40 NEURAMINIDASE. This molecule has the UniProt identifier P03474 (NRAM_INBLE)search. The sample contained 390 residues which is < 90% of the natural sequence. Out of 390 residues 390 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.
