General description
Note: 1 mU = 1 milliunit.
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.
Warning
Toxicity: Standard Handling (A)
Unit Definition
One unit is defined as the amount of enzyme that will catalyze the release of 1.0 µmol p-nitrophenol from p-nitrophenyl-2-acetamido-2-deoxy-3-O-(β-D-galactopyranosyl)-α-D-galactopyranoside per min at 37°C, pH 5.0.
Physical form
In 50 mM sodium phosphate buffer, pH 7.5.
