However, the binding of dCyd to dCK in the presence of ATP or UTP was accompanied by a 1.5- or 3-fold higher quenching amplitude as compared with dCyd alone or in the presence of AMP-PNP

Among the substrates tested, the antitumour drugs gemcitabine and cladribine were bound very tightly by dCK , yielding Kd values of 0.75 and 0.8 microM, respectively, in the presence of UTP
