How are allosteric enzymes controlled?
How are allosteric enzymes controlled? Allosteric regulation of enzymes is crucial for the control of cellular metabolism. Allosteric regulation occurs when an activator or inhibitor molecule binds at a specific regulatory site on the enzyme and induces conformational or electrostatic changes that either enhance or reduce enzyme activity. What is enzyme regulation by phosphorylation? Phosphorylation changes the conformation of an enzyme to a more active or inactive way (e.g. regulation of glycogen phosphorylase). Phosphorylation can take place in the active center of the enzyme. It can change the conformation of this active center, so it can recognize the substrate or...
