  • DOI: 10.1016/0969-2126(93)90005-2
  • Primary Citation of Related Structures:  
    1NSD, 1NSC

  • PubMed Abstract: 
  • Neuraminidase, one of the two surface glycoproteins of influenza virus, cleaves terminal sialic acid residues from glycolipids or glycoproteins. Its crystal structure is known at high resolution, but the mechanism of glycosyl hydrolysis remains unclear.
