expression in Escherichia coli Leuconostoc mesenteroides

Protein Variants

Protein Variants Comment Organism
additional information expression of truncated forms of enzyme containing either catalytic domain CD1 or CD2. Enzymes devoid of CD2 synthesize products containing only alpha-1,6 linkages. Enzymes devoid of CD1 modified alpha-1,6 linear oligosaccharides and dextran acceptors through the formation of alpha-1,2 linkages Leuconostoc mesenteroides

additional information recombinant protein DSR-E synthesizes both alpha-1,6 and alpha-1,2 glucosidic linkages in transglucosylation reactions using sucrose as the donor and maltose as the acceptor. Each of the two catalytic domains is highly regiospecific, CD1 being specific for the synthesis of alpha-1,6 glucosidic bonds and CD2 only catalyzing the formation of alpha-1,2 linkages Leuconostoc mesenteroides ?
