4 * 138325 (alpha), 4 * 125084 (beta), 4 * 44643 (gamma), 4 * 16696 (delta), (alphabetagammadelta)4, calculated from sequence, the phosphorylase kinase enzyme complex is composed of four copies each of four distinct subunits (alpha, beta, gamma and delta). The catalytic protein kinase subunit within this complex is gamma, and its activity is regulated by the three remaining subunits, which are targeted by allosteric activators from neuronal, metabolic, and hormonal signaling pathways. The network of contacts among subunits differs significantly between the nonactivated and phospho-activated conformers of the enzyme, with the latter revealing new interprotomeric contact patterns for the beta subunit, the predominant subunit responsible for activation of the enzyme complex by phosphorylation |
