General annotation (Comments)

Function

Glycosidase that has specific alpha-N-acetylgalactosaminidase activity.

Catalytic activity

Cleavage of non-reducing alpha-(1->3)-N-acetylgalactosamine residues from human blood group A and AB mucin glycoproteins, Forssman hapten and blood group A lacto series glycolipids. Ref.1

Cofactor

Binds 1 NAD+ per subunit. The NAD cannot dissociate By similarity.

Post-translational modification

Predicted to be exported by the Tat system. The position of the signal peptide cleavage has not been experimentally proven.

Sequence similarities

Belongs to the Gfo/Idh/MocA family. Glycosyl hydrolase 109 subfamily.
