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. Partial recombinant protein corresponding to aa6-843 from human PYGB, fused to GST-Tag at N-terminal, expressed in E. coli Swiss/UniProt Accession: P11216.
