RESUMO
A 43-kDa beta-xylosidase from Clostridium cellulolyticum was purified to homogeneity. The enzyme releases xylose from p-nitrophenylxylose and xylodextrins with a degree of polymerization ranging between 2 and 5. The N-terminal amino acid sequence of the enzyme showed homologies with three other bacterial beta-xylosidases. By proton nuclear magnetic resonance spectroscopy, the enzyme was found to act by inverting the beta-anomeric configuration.
