alpha-L-Arabinofuranosidase (EC 3.2.1.55) was purified from culture supernatant of Bacillus subtilis 3-6. The enzyme had a molecular weight of 61,000 and displayed maximum activity at pH 7.0 and 60 degrees C. It released arabinose from O-alpha-L-arabinofuranosyl-(1-->3)-O-beta-D-xylopyranosyl-(1-->4)-D-x ylopyranos e (A1X2), O-beta-D-xylopyranosyl-(1-->4)-[O-alpha-L-arabinofuranosyl-(1-->3)]- O-beta-D-xylopyranosyl-(1-->4)-D-xylopyranose (A1X3), and arabinan, but not from O-beta-D-xylopyranosyl-(1-->2)-O-alpha-L- arabinofuranosyl-(1-->3)-O-beta-D-xylopyranosyl-(1-->4)-O-beta-D-xylopyr anosyl- (1-->4)-D-xylopyranose (A1X4), arabinoxylan, gum arabic, or arabinogalactan.
