CC   -!- FUNCTION: Glycosidase that has specific alpha-N-acetylgalactosaminidase
CC       activity.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Cleavage of non-reducing alpha-(1->3)-N-acetylgalactosamine
CC         residues from human blood group A and AB mucin glycoproteins,
CC         Forssman hapten and blood group A lacto series glycolipids.;
CC         EC=3.2.1.49; Evidence={ECO:0000269|PubMed:17401360};
CC   -!- COFACTOR:
CC       Name=NAD(+); Xref=ChEBI:CHEBI:57540; Evidence={ECO:0000250};
CC       Note=Binds 1 NAD(+) per subunit. The NAD(+) cannot dissociate.
CC       {ECO:0000250};
CC   -!- PTM: Predicted to be exported by the Tat system. The position of the
CC       signal peptide cleavage has not been experimentally proven.
CC   -!- SIMILARITY: Belongs to the Gfo/Idh/MocA family. Glycosyl hydrolase 109
CC       subfamily. {ECO:0000305}.
