Application

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

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.

Packaging

Physical form

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

Unit Definition

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.
