Class of enzymes From Wikipedia, the free encyclopedia
Remove ads
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.
