Application

Adenosine 5′-triphosphate γ-(1-[2-nitrophenyl]ethyl) ester (“Caged” ATP) is used as a photolyzing substrate of luciferase-mediated firefly bioluminescence and other ATP-dependent photolytic processes. Caged ATP has also been used to study the dynamics of ATP-driven linear molecular motors such as myosin Va. Caged ATP is used to study intracellular mechanisms; Irradiation with a short light pulse of 360 nm wavelength releases the parent compound from its cage resulting in a time- and quantity-specific concentration increase of ATP within the cell; Relaxation of muscle fibres by photolysis of caged ATP.

A novel method has been developed for studying the reaction kinetics of the force-generating mechanism in muscle. Inert photolabile precursors of ATP or ADP are incorporated into muscle fibres having their surface membrane barrier removed. The nucleotide is then rapidly

The mechanism of ATP hydrolysis of a shortened variant of the heavy metal-translocating P-type ATPase CopB of Sulfolobus solfataricus was studied. The catalytic fragment, named CopB-B, comprises the nucleotide binding and phosphorylation domains. We demonstrated stoichiometric high-affinity binding of one

The reaction process of firefly bioluminescence was studied by photolyzing caged-ATP to adenosine triphosphate (ATP) within 100 ms. The intensity of luminescence increases markedly to reach a maximum within 1 s, maintains almost the same intensity up to 5 s
