Sucrose utilization

The latest developments in this field and the potential of sucrose-utilizing transglucosidases as synthetic tools to access carbohydrate-based derivatives will be illustrated in the following. [Pg.27]

Potential of Native Sucrose-Utilizing Transglucosidases for Glucoside Synthesis... [Pg.27]

Fig. 2 Main reactions catalyzed by sucrose-utilizing transglucosidases. The synthesis of a-glucans (Glc) linked through either a-1,6 a-1,3, a-1,4, or a-1,2 osidic linkages depending on the enzyme specificity is obtained by glucansucrases. The formation of a-D-glucose-1-phosphate from orthophosphate is obtained using sucrose-phosphorylases. The mechanism involves a double-inversion at the anomeric center via the formation of a covalent P-D-glucosyl enzyme intermediate...

Fig. 3 Overall fold of sucrose-utilizing transglucosidase frran GH13 family, (a) Amylosucrase from N. polysaccharea (PDB 1G5A) [22,27-29]. (b) Sucrose phosphraylase from B. adolescentis (PDB 2GDU) [30,31]. Both enzymes adopt a (P/a)g-barrel arcbitecture. Sucrose is shown as grey spheres to indicate the active site The catalytic (P/a)g-barrel domain (A-domain blue), the C-domain (purple), and the B-domain (green), N-domain (red)...

Enzyme catalytic promiscuity, where enzymes catalyze not only reactions with their natural substrates but also with non-natural substrates, has begun to be recognized as a valuable research and synthesis tool [6-10, 12, 13]. In particular, the catalytic promiscuity displayed by sucrose-utilizing transglucosidases toward a wide range of acceptor molecules has started to be exploited to provide novel synthesis pathways that are currently not available. [Pg.31]

Sucrose-utilizing transglucosidases are produced by bacteria belonging to various genera Leuconostoc, Lactobacillus, Weissella, Streptococcus, Deinococcus, Neisseria, Alteromonas, Pseudomonas, and Bifidobacterium (Table 2). [Pg.32]

The method has proved valuable in studies of the carbohydrate metabolism of microorganisms (105,106), sucrose utilization by fungi (87) and bacteria (22,26), and microbial polysaccharides, e. g., the carbohydrates in yeast cell wall (194,238), polysaccharides of soils (86,104), and polysaccharides from tuberculin and pneumococcus type II (157). [Pg.234]

Fermentation for - ethanol (- sucrose, energy source) is another form of sucrose utilization, which is difficult to evaluate because of the widespread use of ->molasses as C-source. Ethanol is used in edible and pharmaceutical applications. Fuel alcohol is mainly produced from com starch in USA and from sugar cane in Middle and South America. [Pg.287]
