| neuraminidase | <enzyme> Enzyme catalysing cleavage of neuraminic acid residues from oligosaccharide chains of glycoproteins and glycolipids. Since these residues are usually terminal, neuraminidases are generally exo enzymes, although an endoneuraminidase is known. For use as a laboratory reagent, common sources are from bacteria such as Vibrio or Clostridium. A neuraminidase is one of the transmembrane proteins of the envelope of influenza virus.

| haemagglutinin-neuraminidase protein | <protein> A protein found in the capsid of the Sendai virus which is exceptionally good at binding to the cytoplasmic membranes of many animal cells. The protein is therefore used to make fusogenic vesicles for the purpose of delivering therapeutic drugs or other chemicals directly into cells. (09 Oct 1997) |
