Acetyl xylan esterase 4A, Clostridium thermocellum

Acetyl xylan esterase 4A (CtAxe4A), assigned the E.C. number 3.1.1.72, is a derivative of Clostridium thermocellum. It is an enzyme that participates in the deacetylation of xylans and xylo-oligosaccharides. The recombinant CtAxe4A, purified from Escherichia coli, is a modular Carbohydrate Esterase family 4 (CE4) enzyme, with an N-terminal family 6 Carbohydrate Binding Modules (CBM6) (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 1,5 mg/mL.
