Phosphorylation activates or inactivates
WebPhosphorylation often acts as a switch, but its effects vary among proteins. Sometimes, phosphorylation will make a protein more active (for instance, increasing catalysis or letting it bind to a partner). In other cases, phosphorylation may inactivate the protein or cause it to be broken down. [How does a phosphate group do all this?] WebPhosphorylation activates glycogen phosphorylase, causing lots of glucose to be released. The second enzyme that gets phosphorylated is glycogen synthase (GS). This enzyme is involving in building up glycogen, and …
Phosphorylation activates or inactivates
Did you know?
WebPhosphorylation inactivates, whereas dephosphorylation activates, the pro-apoptotic functions of select apoptotic regulators, including the BCL2 family, such as BAD, and transcription factors such as FOXOs. The apoptotic function of the BH3 molecule BAD is exquisitely regulated by phosphorylation. WebPhosphorylation is believed to induce a conformational change in the enzyme resulting in the separation of the N-termini which inactivates the kinase while activating the phosphatase.
