THE X-RAY STRUCTURE OF A COMPLEX OF 5-N-ACETYL-4-AMINO-6-DIETHYLCARBOXAMIDE-4,5-DIHYDRO-2H-PYRAN-2-CARBOXYLIC ACID AND A DRUG RESISTANT VARIANT R292K OF TERN N9 INFLUENZA VIRUS NEURAMINIDASE

The structure was published by Varghese, J.N., Smith, P.W., Sollis, S.L., et al., Sahasrabudhe, A., McKimm-Breschkin, J.L., and Colman, P.M., in 1998 in a paper entitled "Drug design against a shifting target: a structural basis for resistance to inhibitors in a variant of influenza virus neuraminidase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1998.

The experimental data on which the structure is based was not 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.
