alpha-N-Acetylgalactosaminidase 129A, Bifidobacterium bifidum

alpha-N-Acetylgalactosaminidase 129A (BbNga129A), assigned the E.C. number 3.2.1.49, is a derivative of Bifidobacterium bifidum. It is an enzyme that cleavage of non-reducing 1,3-alpha-N-acetylgalactosamine residues from human blood group A and AB mucin glycoproteins. The recombinant BbNga129A, purified from Escherichia coli, is a single-domain Glycoside Hydrolase family 129 (GH129) enzyme (see more details at www.cazy.org).The protein is supplied in a solution containing 35 mM NaHepes buffer (pH 7.5), 750 mM NaCl, 200 mM Imidazole, 3.5 mM CaCl2, and 25% (v/v) glycerol, at a concentration of 1 mg/mL.
