ATP-gamma-S is a kinase substrate and inhibitor of ATP-dependent enzyme systems. Hydrolyzed very slowly by phosphatases and most ATPases. Once thiophosphorylated, proteins are resistant to protein phosphatases. P2 purinergic receptor agonist.
- Cited in over 30 publications
- Purity > 80%
- Soluble in water to 10 mM

Kinase reaction reagent to be used with Anti-Thiophosphate ester antibody [51-8] ab92570 rabbit monoclonal to thiophosphate ester for the identification of direct kinase substrates as mentioned in Allen JJ et al. Nat Methods 4:511-6 (2007).
After the kinase of interest has accepted ATP-γ-S, p-Nitrobenzyl mesylate (p-Nitrobenzyl mesylate, Alkylation reagent ab138910) can be used to alkylate the thiophospholyation site on the substrates. A thiophosphate ester rabbit monoclonal antibody (Anti-Thiophosphate ester antibody [51-8] ab92570) is introduced to identify the tagged substrates.
For western blot analysis, we used ATPγS or A*TPγS analogs at a concentration of 1 mM. For kinetic measurements, ATPγS or A*TPγS analog concentration varied from 0.1 μM to 250 μM. See Allen JJ et al. Nat Methods 4:511-6 (2007); Supp. Material.
