| Outline of Final Research Achievements |
Recently three novel arabinosidases have been found in Bifidobacteria and the orthologs of the enzymes exist on the genome of the plant pathogenic bacterium, Xanthomonas euvesicatoria (Xcv). In this work, the three orthologs (XcvHypBA1, XcvHypBA2, XcvHypAA)derived from Xcv were analyzed to elucidate their functions. As a result, it is revealed that the three enzymes work together and have functions to degrade arabino-oligosaccharides on glycoproteins such as extensin and lectin that are thought to be involved in the plant immune system. The expression of the enzyme genes were highly induced in infected plants, suggesting that the three enzymes might play an important role in pathogenicity.
