General annotation (Comments)

Function

Developmentally regulated neuraminidase implicated in parasite invasion of cells. May contribute to the pathology during T.cruzi infection by cleaving sialic acid from cells of the immune system.

Catalytic activity

Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-(2->8)- glycosidic linkages of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids, colominic acid and synthetic substrates.

Developmental stage

Mammalian stage of parasite.

Miscellaneous

The parasite mammalian stage surface antigen exhibits extensive antigenic diversity.

Sequence similarities

Belongs to the glycosyl hydrolase 33 family.
