8-Azido-ATP  (Synonyms: 8-Azidoadenosine 5'-triphosphate; 8-N3-ATP)

8-Azido-ATP, a photoreactable nucleotide analog, is useful for the identification of proteins, such as DNA-dependent RNA polymerase^[1]. 8-Azido-ATP is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

8-Azido-ATP can be used to identify the viral RNA polymerase on the basis of the ability of the analog to inhibit transcription activity associated with rotavirus particles on exposure to UV light^[1].
8-Azido-ATP (azido-ATP) decreases viral transcription in a dose-dependent manner^[1].
8-Azido-ATP blocks Kir6.2ΔC26 currents rather less potently than ATP, half-maximal inhibition (Ki) occurring at 2.8 ± 0.4 mM (n = 6) compared with 172 ± 7 mM for ATP (n = 6). The Hill coefficients were 0.9 ± 0.2 for 8-azido-ATP and 1.3 ± 0.1 for ATP^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
