Examples
In the final step of glycolysis, pyruvate kinase transfers a phosphoryl group from phosphoenolpyruvate to ADP, generating ATP and pyruvate.
Kinases properly orient their substrate and the phosphoryl group within their active sites, which increases the rate of the reaction.
The phosphoryl groups, starting with the group closest to the ribose, are referred to as the alpha (α), beta (β), and gamma (γ) phosphates.
