In enzymology, an alpha,alpha-trehalose phosphorylase (EC 2.4.1.64) is an enzyme that catalyzes the chemical reaction

alpha,alpha-trehalose + phosphate D-glucose + beta-D-glucose 1-phosphate

Thus, the two substrates of this enzyme are trehalose and phosphate, whereas its two products are D-glucose and beta-D-glucose 1-phosphate.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is alpha,alpha-trehalose:phosphate beta-D-glucosyltransferase. This enzyme is also called trehalose phosphorylase. This enzyme participates in starch and sucrose metabolism.
