CRYSTALLINE MUSCLE PHOSPHORYLASE

The action of crystalline muscle phosphorylase on outer chains of glycogen and amylopectin.

Degradation of biological macromolecules may take place by one of three enzymatic mechanisms. In the first (single chain), the enzyme remains attached to the substrate until a limit of degradation is reached before a new substrate molecule or unit is attacked. The second mechanism would be a partial or incomplete single chain mechanism. During an encounter between enzyme and substrate, several ...

The muscle phosphorylase b kinase reaction.

The conversion of skeletal muscle phosphorylase b to phosphorylase a is catalyzed by an enzyme requiring ATP’ and a divalent metal (1). In this reaction phosphate is transferred from the nucleotide to phosphorylase, and a dimerization of the enzyme occurs (2). The dimer-monomer relationship existing between phosphorylases a and b was noted originally by Keller and Cori in their work on the phos...
