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: WebPhosphorylase b kinase catalyzes the phosphorylation of serine in certain substrates, including troponin I. The alpha chain may bind calmodulin. Phosphorylase kinase is a …
