D-塔格糖是一种天然的低能量填充型甜味剂,具有抑制高血糖,改善肠道菌群和不致龋齿等多种生理功效。D-塔格糖是一种稀有糖,通常利用化学转化或生物转化方法进行大量生产。L-阿拉伯糖异构酶(L-arabinose isomerase, AI)能分别催化L-阿拉伯糖和D-半乳糖异构为L-核酮糖和D-塔格糖,AI是目前生物法生产新型功能性因子D-塔...
d-Arabinose isomerase from Klebsiella pneumoniae 40bXX was purified 12-fold with a 62.5% yield indicated by its electrophoretic homogeneity. The purified enzyme showed the highest activities toward d-... 详情 Characterization of a recombinant L-fucose isomerase from Caldicellulosiruptor saccharolyticus th...
以D-半乳糖为原料,酶催化合成D-塔格糖逐渐成为主流合成方法[29]。该方法用到的核心酶是L-阿拉伯糖异构酶(L-arabinose isomerase,AI),由于D-半乳糖和 L-阿拉伯糖结构具有一定的相似性,因此AI 能够催化D-半乳糖转化为D-塔格糖[30]。为了...
This chapter discusses the determination of D-arabinose isomerase. Two assay methods may be employed. The first utilizes the cysteine–carbazole test for ketopentoses to determine the quantity of D-ribulose formed after incubation of D-arabinose and enzyme. The second spectrophotometrically measures ...

Scientists are working on these two kinds of isomerases since 1953. The first article reported by Cohen in 1953 considered the inventor of L-FI & D-AI in which first time cell-free extract from E. coli was used to transform not only L-fucose to L-fuculose but also D-arabinose to D...
