AMP-PNP  (Synonyms: Adenylyl imidodiphosphate)

AMP-PNP (Adenylyl imidodiphosphate) is a non-hydrolyzable ATP analog. AMP-PNP binds to ATP binding sites competely but is not hydrolyzed by enzymes, providing stable experimental conditions for studying ATP-dependent processes. AMP-PNP can also be used to study enzyme activity, kinase regulation, DNA/RNA metabolism, ion channel function, and protein complex assembly^[1][2][3][4].

AMP-PNP (100 nM-3.3 mM) competitively elutes BtuCD(EQNC)-F from ATP-agarose beads, inhibiting the ATPase activity of both wild-type and mutant BtuCD-F^[1].
AMP-PNP (1.9-2 mM, 0-15 min) fails to inhibit the ATP-dependent scanning process of the 5' leader sequence of eukaryotic mRNA^[2].
AMP-PNP (1 μM-1 mM) concentration-dependently blocked the single ATP-sensitive potassium channels (KATP channels) in the skeletal muscles of mice^[4].
