MeSH definition : An enzyme of the PHOSPHORYLASES family that catalyzes the degradation of starch, a
mixture of unbranched AMYLOSE and branched AMYLOPECTIN compounds. This phosphorylase
from plants is the counterpart of GLYCOGEN PHOSPHORYLASE in animals that catalyzes
the reaction of inorganic phosphate on the terminal alpha-1,4-glycosidic bond at the
non-reducing end of glucans resulting in the release of glucose-1-phosphate.;
