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

-
?
additional information
?
-
the formation of alpha-(1->2) branching is kinetically controlled and can occur onto vicinal alpha-(1->6)-linked D-Glc residues. The branching process is stochastic and the enzyme acceptor site can accommodate both linear and poly-branched acceptors
