Enzymatic synthesis of polyglucosylfructosides from sucrose alone by a novel α-glucosidase isolated from the digestive juice of Archachatina ventricosa (Achatinideae)

Acceptor Specificity and Transfer Efficiency of a β-Glycosidase from the China White Jade Snail

“…Some glycosidases with transglycosylation activity have been reported to accept disaccharides as the acceptors in the synthesis of some oligosaccharides that were larger than trimers. 31,32) However, the transfer products were a polysaccharide mixture including trisaccharides, tetrasaccharide, pentasaccharides and larger oligosaccharides, which needed at least one additional isolation step to obtain the individual oligosaccharide. Although G I could only accept monosaccharide acceptors, it could be a useful tool in the production of some heterodisaccharides containing different monosaccharides due to its broad monosaccharide acceptor specificity.…”

Purification and characterization of the α-glucosidase produced by thermophilic fungus Thermoascus aurantiacus CBMAI 756

“…Similar differences were also observed for the molar mass of -glucosidases from Chaetomium thermophilum var. coprophilum, Acremonium implicatum IFO30538, the yeast Schizosaccharomyces pombe, and Archachatina ventricosa, which contained 14, 42.8, 91, and 25% of carbohydrates, respectively (Yamamoto et al, 2004;Okuyama et al, 2005;Giannesi et al, 2006;Soro et al, 2007). Several procedures have been described for the purification of -glucosidases from different origins and the molecular masses detected are in the range of 22-1,120 kDa, which indicate the enormous variability of these enzymes (Anindyawati et al, 1998;Kashiwabara et al, 2000;Nashiru et al, 2001;Kato et al, 2002;Faridmoayer and Scaman, 2004;Torre-Bouscoulet et al, 2004;Yamamoto et al, 2004;Okuyama et al, 2005;Ezeji and Bahl, 2006;Giannesi et al, 2006;Naested et al, 2006).…”

“…coprophilum (Giannesi et al, 2006), Aspergillus nidulans (Kato et al, 2002), A. niger (Shimba et al, 2009), A. implicatum IFO30538 (Yamamoto et al, 2004), A. ventricosa (Soro et al, 2007), Xantophyllomyces dendrorhous (Fernánez-Arrojo et al, 2007), and recombinant -glucosidase (TtGluA) from Thermoanaerobacter tengcongensis MB4 (Zhou et al, 2009). The transglycosylation reaction is an important property of -glucosidases in the synthesis of sugars with commercial application, which highlights the importance of the -glucosidase from T. aurantiacus studied in this article.…”

Transglucosylation reaction of amylomaltase for the synthesis of anticariogenic oligosaccharides

“…Maltogenic amylase can produce ␣-(1-6) maltooligosylsucrose products that show a low sweetness, high hygroscopicity, low Maillard reactivity, and high acid and heat stability [4]. ␣-Glucosidases from the digestive juice of a snail has been used to produce ␣-(1-4) maltooligosylsucroses from sucrose as the sole substrate [7], while the wild type and mutated ␣-glucosidases from Bacillus sp. SAM 1606 produced ␣-(1-6) maltooligosylsucrose (theanderose) as the major product [8].…”
