CC -!- FUNCTION: Catalyzes the removal of sialic acid (N-acetylneuraminic
CC acid) moieties from glycoproteins and glycolipids. To be active, it is
CC strictly dependent on its presence in the multienzyme complex. Appears
CC to have a preference for alpha 2-3 and alpha 2-6 sialyl linkage.
CC {ECO:0000256|ARBA:ARBA00037235}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of alpha-(2->3)-, alpha-(2->6)-, alpha-
CC (2->8)- glycosidic linkages of terminal sialic acid residues in
CC oligosaccharides, glycoproteins, glycolipids, colominic acid and
CC synthetic substrates.; EC=3.2.1.18;
CC Evidence={ECO:0000256|ARBA:ARBA00000427};
CC -!- SUBUNIT: Interacts with cathepsin A (protective protein), beta-
CC galactosidase and N-acetylgalactosamine-6-sulfate sulfatase in a
CC multienzyme complex. {ECO:0000256|ARBA:ARBA00038519}.
CC -!- SUBCELLULAR LOCATION: Cytoplasmic vesicle
CC {ECO:0000256|ARBA:ARBA00004541}. Lysosome lumen
CC {ECO:0000256|ARBA:ARBA00004227}. Lysosome membrane
CC {ECO:0000256|ARBA:ARBA00004207}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004207}; Lumenal side
CC {ECO:0000256|ARBA:ARBA00004207}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 33 family.
CC {ECO:0000256|ARBA:ARBA00009348}.
