Crystal Structure of Maltose Phosphorylase from Lactobacillus Brevis: Unexpected Evolutionary Relationship with Glucoamylases.
Structure, 9:689-, 2001

PubMed Abstract: Maltose phosphorylase (MP) is a dimeric enzyme that catalyzes the conversion of maltose and inorganic phosphate into beta-D-glucose-1-phosphate and glucose without requiring any cofactors, such as pyridoxal phosphate. The enzyme is part of operons that are involved in maltose/malto-oligosaccharide metabolism. Maltose phosphorylases have been classified in family 65 of the glycoside hydrolases. No structure is available for any member of this family.
