Nucleotide exchange from ADP to ATP is crucially important for both the regulation and motility of the molecular motor kinesin 1,2,3,4,5. At least three key events occur during this step.

Energy is released from ATP when the end phosphate is removed. Once ATP has released energy, it becomes ADP (adenosine diphosphate), which is a low energy molecule. ADP can be recharged back into ...

The enzymatic removal of a phosphate group from ATP to form ADP releases a huge amount of energy which is used by the cell in several metabolic processes as well as in the synthesis of ...

During cellular respiration, energy is captured when a phosphate is added to ADP (adenosine diphosphate ... requires six separate ATP-driven steps; while convincing models do allow for prebiotic ...

Adenosine diphosphate (ADP) or adenosine triphosphate (ATP)-containing important biological molecules can modify macromolecules like proteins and nucleic acids to alter their function in the cell.

Here we examine the roles that purines play as extracellular signaling molecules, with a particular focus on ATP, adenosine diphosphate (ADP), and adenosine. The first reports of purinergic ...
