Maltoheptaose hydrate, a maltooligosaccharide composed of seven glucose units, serves as an activator of phosphorylase B for the preparation of heptulose-2-phosphate.
Phosphorylase Kinase β-Subunit Fragment (420-436) is a peptide fragment (430-436) derived from the β-Subunit of phosphorylase kinase. Phosphorylase kinase, a serine threonine-specific protein kinase, plays a crucial role in the activation of glycogen phosphorylase for the release of glucose-1-phosphate from glycogen[1].
