additional information | during lactose conversion at 70°C galactosyl transfer to acceptors other than water competes efficiently with complete hydrolysis of substrate. This process leads to transient formation of a range of new products, mainly disaccharides and trisaccharides, and shows a marked dependence on initial substrate concentration and lactose conversion. The molar ratio of trisaccharides to disaccharides is maximal at an early stage of reaction and decreases directly proportional to increasing substrate conversion. The major transgalactosylation products of SsbetaGl are beta-D-Galp-(1->3)-Glc and beta-D-Galp-(1->6)-Glc, and beta-D-Galp-(1->3)-lactose and beta-D-Galp-(1-->6)-lactose. The enzyme accumulates beta(1-->6)-linked glycosides, particularly allolactose, at a late stage of reaction | Saccharolobus solfataricus | ? | - |
