General annotation (Comments)

Function

Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.

Catalytic activity

(1,4-alpha-D-glucosyl)(n) + phosphate = (1,4-alpha-D-glucosyl)(n-1) + alpha-D-glucose 1-phosphate.

Cofactor

Pyridoxal phosphate.

Subunit structure

Homodimer.

Sequence similarities

Belongs to the glycogen phosphorylase family.
