Opis

General description

Phosphorylase kinase contains four subunits each containing an α, β, γ, and sigma component. The sigma component binds 4 calcium molecules and is termed calmodulin while the γ unit acts as the catalytic subunit. [1]

Application

Phosphorylase kinase from rabbit muscle has been used in a study to assess features of glycogen phosphorylase. [2] It has also been used in a study to investigate the activation of different forms of muscle phosphorylase kinase by actin. [3]

Physical form

Lyophilized powder containing (NH₄)₂SO₄, sucrose, β-glycerophosphate and dithioerythritol

Other Notes

One unit will form 1.0 μmolar unit of phosphorylase a from phosphorylase b per min at pH 7.7 at 30°C in the presence of ATP.
