Alpha,alpha-trehalose synthase

Alpha,alpha-trehalose synthase (, trehalose synthase, trehalose synthetase, UDP-glucose:glucose 1-glucosyltransferase, TreT, PhGT) is an enzyme with systematic name ADP-glucose:D-glucose 1-alpha-D-glucosyltransferase. This enzyme catalyses the following chemical reaction


 * ADP-glucose + D-glucose $$\rightleftharpoons$$ alpha,alpha-trehalose + ADP

This enzyme requires Mg2+ for maximal activity.
