Ligands: BMA, CA, GOL, NAG Related: 3nss, 3san Gene: NA (Influenza A virus) Activity: Exo-alpha-sialidase, with EC number 3.2.1.18 Resources: FirstGlance, OCA, RCSB, PDBsum Publication Abstract from PubMed There are 9 serotypes of neuraminidase (NA) from influenza A virus (N1 to N9), which are classified into two groups based on primary sequences (groups 1 and 2). The structural hallmark of the two groups is the presence or absence of an extra 150-cavity (formed by the 150-loop) in the active site. Thus far, structures of NAs from 6 out of the 9 serotypes have been solved. Here, we solved the N5 structure, the last unknown structure group 1 serotype with a unique Asn147 residue in its 150-loop, demonstrating that it has an extended 150-cavity that closes upon inhibitor binding. Influenza a virus n5 neuraminidase has an extended 150-cavity.,Wang M, Qi J, Liu Y, Vavricka CJ, Wu Y, Li Q, Gao GF J Virol. 2011 Aug;85(16):8431-5. Epub 2011 Jun 8.
