In enzymology, a maltose phosphorylase (EC 2.4.1.8) is an enzyme that catalyzes the chemical reaction

maltose + phosphate D-glucose + beta-D-glucose 1-phosphate

Thus, the two substrates of this enzyme are maltose 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 maltose:phosphate 1-beta-D-glucosyltransferase. This enzyme participates in starch and sucrose metabolism.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1H54.
