Abstract

Recombinants, Cel6 from Coprinopsis cinerea (CcCel6)A, -B, and -C, were expressed by Escherichia coli. These enzymes produced cellobiose from phosphoric acid-swollen cellulose. When Avicel was used as the substrate, CcCel6A showed higher activity toward the substrate than CcCel6B or -C. In reaction with carboxymethylcellulose, CcCel6B and -C hydrolyzed the substrate, whereas CcCel6A failed to react.
