The English-language version of the first reference can be found on pages 388-399 of the above. This domain has been named NEW3 but its actual function is not known. 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 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.
