General annotation (Comments)

Function

Alpha-galactosidase that specifically removes branched alpha-1,3-linked galactose residues present in blood group B antigens. Has no activity toward linear alpha-1,3-linked galactose residues.

Catalytic activity

Hydrolysis of terminal, non-reducing branched (1->3)-alpha-D-galactosidic residues, producing free D-galactose. Ref.1 Ref.2

Hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha-D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids. Ref.1 Ref.2

Biotechnological use

Specifically cleaves the branched blood group B antigen at neutral pH with low consumption of recombinant enzyme. It is therefore a good candidate to participate in the development of universal red blood cells by removing blood group B antigen.

Sequence similarities

Belongs to the glycosyl hydrolase 110 family. A subfamily.

Contains 6 PbH1 repeats.
