WebDec 4, 2024 · Phosphorylase kinase is a polymer of 16 subunits, four each of alpha, beta, gamma and delta. The alpha subunit includes the skeletal muscle and hepatic isoforms, and the hepatic isoform is encoded by this gene. The beta subunit is the same in both the muscle and hepatic isoforms, and encoded by one gene. WebPhosphorylase b is a dimer, usually exists in inactive form in the skeletal muscles. [ 1] [ 2] Equilibrium exists between an active relaxed (R) state and a less active tense (T). …

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: WebMar 1, 2003 · Subunit Hexadecamer of 4 heterotetramers, each composed of alpha, beta, gamma, and delta subunits.
