WebPhosphorylase b kinase (PhK) is a regulatory enzyme in the activation cascade of glycogenolysis. By phosphorylating and thus activating glycogen phosphorylase, PhK … Phosphorylase kinase is a 1.3 MDa hexadecameric holoenzyme, though its size can vary somewhat due to substitution of different subunit isoforms via mRNA splicing. It consists of four homotetramers each comprised four subunits (α,β,δ,γ). Only the γ subunit is known to possess catalytic activity, while the others serve regulatory functions. Due to the instability of the regulatory subunits in solution, only the γ subunit has been crystallized individually:
