Hence, this enzyme has one substrate, maltose, and one product, alpha,alpha-trehalose.
This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring other groups. The systematic name of this enzyme class is maltose alpha-D-glucosylmutase. Other names in common use include trehalose synthase, and maltose glucosylmutase. This enzyme participates in starch and sucrose metabolism.
