Recombinant, Streptococcus pneumoniae Endo-α-N-acetylgalactosaminidase expressed in E. coli. Catalyzes the hydrolysis of the unsubstituted Galβ1,3GalNAc core disaccharide attached to serine or threonine residues of glycopeptides and glycoproteins to afford free oligosaccharides. For carbohydrates containing sialic acid or fucose, pretreatment with neuraminidase or fucosidase is required.
