Maltose alpha-D-glucosyltransferase explained

Maltose α-D-glucosyltransferase
Ec Number:	5.4.99.16
Go Code:	0047471

In enzymology, a maltose α-D-glucosyltransferase is an enzyme that catalyzes the chemical reaction

maltose

\rightleftharpoons alpha,alpha-trehalose

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.
