synthesis |
the enzyme (TreS) produced from Acidiplasma spMBA-1 can catalyze a considerable amount of maltose into trehalose in a single step reaction. Maltose is a relatively cheap substrate. Hence, TreS can be used as an alternative commercial enzyme to produce trehalose commercially. A significant amount of glucose is being produced as a byproduct which hinders the production of commercial trehalose. If it is possible to suppress glucose production by genetic modifications, it could enhance trehalose production |
