protein vertebrate-like neuraminidase PR:000022007 sialidase A protein that is a glycohydrolytic enzyme, which removes sialic acid residues from a variety of sialoglycoconjugates. Sialidases have highly conserved active site residues, the F/YRIV/P motif in the N-terminal part and the Asp boxes (consensus S/TXD(x)GxTW/F present as three to five repeat in the protein) similar to their viral and bacterial counter parts. protein Category=family.
