In order to liberate arabinose from arabinose-containing polysaccharides such as arabinan, arabinoxylan, and arabinogalactan, α-L-arabinofuranosidase was investigated. An α-L-arabinofuranosidase II was purified from the culture fluid of Bacillus sp. No. 430,which was isolated from the soil of sugar cane fields. The process of purification was as follows; salting out by ammonium sulfate, first DEAE-cellulose, second DEAE-cellulose, QAE-Sephadex A-50,DEAE-Toyopearl 650 S, and Sephadex G-75 column chromatography. The enzyme was highly purified by the method of disc gel electrophoresis. The purified enzyme had the maximum reactivity at pH 7.0 and 40℃. The enzyme was partially inhibited by Cu^<2+>, Cd^<2+>, α, α′-dipyridyl, iodoacetic acid, and p-chloromercuribenzoic acid. The highly purified enzyme was confirmed to liberate L-arabinose from beet arabinan, arabinogalactan, arabinoxylan, and p-nitrophenyl α-L-arabinofuranoside. The reaction product was paper chromatographically demonstrated to be L-arabinose only. The purified enzyme was inactive for p-nitrophenyl α-, β-D-galactopyranosides and p-nitrophenyl β-D-xylopyranoside. And thus, it was characterized as α-L-arabinofuranosidase which was exo-arabinanase. High purity of xylan from sugar cane bagasse or galactans from coffee bean and soybean was obtained with the enzyme.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3891"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
