ID   2.4.1.1
DE   glycogen phosphorylase.
AN   amylophosphorylase.
AN   muscle phosphorylase a and b.
AN   polyphosphorylase.
CA   [(1->4)-alpha-D-glucosyl](n) + phosphate = [(1->4)-alpha-D-glucosyl](n-1)
CA   + alpha-D-glucose 1-phosphate.
CC   -!- This entry covers several enzymes from different sources that act in
CC       vivo on different forms of (1->4)-alpha-D-glucans.
CC   -!- Some of these enzymes catalyze the first step in the degradation of
CC       large branched glycan polymers - the phosphorolytic cleavage of
CC       alpha-1,4-glucosidic bonds from the non-reducing ends of linear
CC       poly(1->4)-alpha-D-glucosyl chains within the polymers.
CC   -!- The enzyme stops when it reaches the fourth residue away from an
CC       alpha-1,6 branching point, leaving a highly branched core known as a
CC       limit dextrin.
CC   -!- The description (accepted name) of the enzyme should be modified for
CC       each specific instance by substituting 'glycogen' with the name of
CC       the natural substrate, e.g. maltodextrin phosphorylase, starch
CC       phosphorylase, etc.
