Purification and characterization of a cellulase from the giant snail achatina fulica

Abstract

A cellulase with activity as a cellobiohvdrolase [EC 3.2.1.91] was purified from the intestinal juice of the giant snail Achatina fulica. The enzyme (M/r = about 23,000, and pI= about 5.3) also had a weak β-glucosidase activity. The amino acid sequence of the N-terminal 20 amino acids was analyzed, and no similarity was noted for sequences of other known cellobiohydrolases. © 1996, Taylor & Francis Group, LLC.
