alpha-N-Acetylgalactosaminidase 109A, Elizabethkingia meningoseptica

alpha-N-Acetylgalactosaminidase 109A (EmNga109A), assigned the E.C. number 3.2.1.49, is a derivative of Elizabethkingia meningoseptica. It is an enzyme that participates in the cleavage of non-reducing 1,3-alpha-N-acetylgalactosamine residues from human blood group A and AB mucin glycoproteins. The recombinant EmNga109A, purified from Escherichia coli, is a single-domain Glycoside Hydrolase family 109 (GH109) 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 0,25 mg/mL. Bulk quantities of this product can be made available upon request. Shipping Conditions: Shipping: Dry Ice to RT. Storage Conditions: -30°C to -15°C. Class: Glycoside Hydrolase.
