Transphosphorylation

Transphosphorylation is a chemical reaction in which a phosphate group or a phosphono group is transferred between a substrate and a receptor.^[1] There are various phosphate esters in living body including nucleic acid, and phosphorylation reaction related to their synthesis and interconversion is the basis of biochemical reaction.^[2][3] In most cases, ATP is the substrate of the phosphate group as a substrate and the enzyme that catalyzes these reactions is referred to as kinase.^[4]
