It is found on proteins which are bacterial galactosidases [1]. The domain is associated with the NPCBM family, Pfam:PF08305, a novel putative carbohydrate binding module found at the N-terminus of glycosyl hydrolases.

exo-alpha-sialidase (GH33 Family)  M-CSA #835

Exo sialidases (neuraminidases) catalyse the removal of terminal sialic acid residues in oligosaccharides, glycoproteins, glycolipids and synthetic substrates to release free sialic acid. This class function to release sialic acids for use as carbon and energy sources for non-pathogenic bacterium while in pathogenic microorganisms, sialidases have been suggested to be pathogenic factors.
