Adenosine 5′-Triphosphate (ATP) is nucleotide used as a substrate for many ATP-dependent enzyme systems, including protein kinases, protein phosphatases and DNA ligation. No detectable RNase, DNase, phosphatase or protease contaminating activities.
P 2 purinergic agonist; increases activity of Ca 2+-activated K + channels; substrate for ATP-dependent enzyme systems
Adenosine-5’-triphosphate (ATP) is a vital for metabolic energy storage and transfer. It serves as a reaction coenzyme and substrate for many kinases.

The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis).
1 sty 1996 · In regard to energy transfer, the critical part of the ATP molecule is its phosphate tail, and, in particular, its two terminal phosphate groups (P and y phosphates). Each is linked to the neighboring phosphate by an acid anhydride link.
22 lut 2021 · Several IR bands of ATP or 18O-labeled ATP were found to be assignable to vibrations predominantly involving one of the three phosphate groups. Frequency shifts of such localized vibrations on complex formation are useful to investigate the sites of coordination of Mg2+ to ATP.
