- Cellobiose phosphorylase
In
enzymology , a cellobiose phosphorylase (EC number|2.4.1.20) is anenzyme that catalyzes thechemical reaction :cellobiose + phosphate ightleftharpoons alpha-D-glucose 1-phosphate + D-glucose
Thus, the two substrates of this enzyme are
cellobiose andphosphate , whereas its two products arealpha-D-glucose 1-phosphate andD-glucose .This enzyme belongs to the family of
glycosyltransferase s, specifically the hexosyltransferases. The systematic name of this enzyme class is cellobiose:phosphate alpha-D-glucosyltransferase. This enzyme participates instarch and sucrose metabolism .tructural studies
As of late 2006, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|2CQS and PDB link|2CQT.
