STRUCTURAL MECHANISM FOR GLYCOGEN PHOSPHORYLASE CONTROL BY PHOSPHORYLATION AND AMP
Overview
The crystal structures of activated R state glycogen phosphorylase a (GPa), and R and T state glycogen phosphorylase b (GPb) complexed with AMP have, been solved at 2.9 A, 2.9 A and 2.2 A resolution, respectively. The, structure of R state GPa is nearly identical to the structure of, sulphate-activated R state GPb, except in the region of Ser14, where there, is a covalently attached phosphate group in GPa and a non-covalently, attached sulphate group in GPb. The contacts made by the N-terminal tail, residues in R state GPa at the subunit interface of the functionally, active dimer are similar to those observed previously for T state GPa. The, quaternary and tertiary structural changes on the T to R transition allow, these interactions to be relayed to the catalytic site in R state GPa. ... [(full description)]
