Effect of divalent metal cations upon the fluorescence and phosphorescence properties of adenosine triphosphate.
The fluorescence and phosphorescence properties of various divalent metal cations and adenosine triphosphate (ATP) dissolved in 1:1 volume by volume of ethylene glycol and water at 77 K have been studied. The present results indicate that Co2+, Ni2+ and Mn2+ quench the phosphorescence of ATP, whereas the fluorescence and the phosphorescence decays are not or only slightly affected. On the other hand, Ca2+ and Mg2+ have no remarkable effect upon the fluorescence and phosphorescence properties.
