Application

Adenosine 5′-(β,γ-imido)triphosphate lithium salt hydrate has been used in a study to research the effects of monovalent cations Li+, Na+, K+, NH4+, Rb+ and Cs+ on the solid and solution structures of the nucleic acid components. Adenosine 5′-(β,γ-imido)triphosphate lithium salt hydrate has also been used in a study to determine that antidepressants inhibit interferon-γ-induced microglial production of IL-6 and nitric oxide.

Biochem/physiol Actions

A non-hydrolyzable ATP analog. AMP-PNP competitively inhibits ATP-dependent enzyme systems, such as glutamine synthetase. It inhibits a number of enzymes which require the hydrolysis of ATP such as DNA topoisomerase II, SV40 large T-antigen helicase and a number of kinases. Blocks ATP-sensitive calcium-dependent potassium channels.

Caution

AMP-PNP is very unstable in acidic conditions; rapidly hydrolyzes to the phosphoramidate and inorganic phosphate.

Reconstitution

A 10 mg/mL stock solution may be made, aliquoted and stored at -70 °C for up to 3 months.

Type IIA topoisomerases control DNA supercoiling and disentangle chromosomes through a complex ATP-dependent strand-passage mechanism. Although a general framework exists for type IIA topoisomerase function, the architecture of the full-length enzyme has remained undefined. Here we present the structure of
