FluorescentNucleosideTriphosphatesforSingleMoleculeEnzymology2

1.1 Selection of the Labeling PositionFluorescent adenine and guanine nucleotides have been widely used to report upon binding, protein release and structural changes (6–11). Fluorophores are sensitive probes, easily used at submicromolar concentrations, and can have properties that report rapidly, even on small perturbations in the region of the fluorophore. Thus, ATP and analogs have been modified with ......阅读全文
