The beta-1,3-xylosidase gene (xloA) of Vibrio sp. strain XY-214 was cloned and expressed in Escherichia coli. The xloA gene consisted of a 1,608-bp nucleotide sequence encoding a protein of 535 amino acids with a predicted molecular weight of 60,835. The recombinant beta-1,3-xylosidase hydrolyzed beta-1,3-xylooligosaccharides to D-xylose as a final product.
对弧菌属XY-214菌株的β-1,3-木糖苷酶基因(xloA)进行了克隆,并在大肠杆菌中表达。xloA基因由1608个碱基对的核苷酸序列组成,编码一种含有535个氨基酸的蛋白质,预测分子量为60835。重组β-1,3-木糖苷酶将β-1,3-木寡糖水解为最终产物D-木糖。
