More generally, phosphorylases are enzymes that catalyze the addition of a phosphate group from an inorganic phosphate (phosphate+hydrogen) to an acceptor. Do not confuse this enzyme with a phosphatase or a kinase. A phosphatase removes a phosphate group from a donor, while a kinase transfers a phosphate group from a donor (usually ATP) to an acceptor.
All known phosphorylases share catalytic and structural properties .
Phosphorylase a is the active form of glycogen phosphorylase that is derived from the phosphorylation of the inactive form, phosphorylase b.
