1939 G. T. Cori et al. in Jrnl. Biol. Chem. 127 771 Various mammalian tissues..contain an enzyme which can be extracted with water and which forms glucose-1-phosphoric ester..from glycogen and inorganic phosphate... This enzyme, which will be referred to as phosphorylase, initiates the degradation of glycogen.

1955 Sci. News Let. 7 May 297/1 Use of muscle to do work and its recovery depends upon the chemical action of an enzyme, phosphorylase, which is found in muscle.

1971 Nature 19 Feb. 529/1 The breakdown of glycogen..is controlled by the activity of glycogen phosphorylase. This enzyme exists in two states: phosphorylase b..is a form of low concentration... Under the action of phosphorylase kinase it is phosphorylated at one serine residue in each of the four subunits, to give the highly active phosphorylase a.

1989 Jrnl. Developmental Physiol. 11 361/2 Phosphorylase activity was assayed in the direction of glycogen synthesis.

2000 Isis 91 731 Polynucleotide phosphorylase was acknowledged both as an important enzymological achievement and because it became a tool for elucidating the genetic code.
