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.
Bloom (BLM) syndrome is an autosomal recessive disorder characterized by an increased risk for many types of cancers. Previous studies have shown that BLM protein forms a hexameric ring structure, but its oligomeric form in DNA unwinding is still not
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

To ensure their stable inheritance by daughter cells during cell division, bacterial low-copy-number plasmids make simple DNA segregating machines that use an elongating protein filament between sister plasmids. In the ParMRC system of the Escherichia coli R1 plasmid, ParM, an
The ATP-binding cassette (ABC) transporter BtuCD mediates the uptake of vitamin B(12) across the inner membrane of Escherichia coli. Previous structures have shown the conformations of apo states, but the transport mechanism has remained unclear. Here we report the 3.5 Å

Carbon catabolite repression (CCR) is a widespread phenomenon in many bacteria that is defined as the repression of catabolic enzyme activities for an unfavorable carbon source by the presence of a preferable carbon source. In Streptomyces, secondary metabolite production often
