Abstract In the presence of copper certain 2,2′-bipyridyls show antimycoplasmal activity, whereas copper itself causes a toxic effect. In this paper results are presented to elucidate the mechanism of copper uptake in the presence of 2,9-dimethyl-1,10-phenanthroline. The time course of copper and/or ligand uptake under the applied conditions is consistent with a carrier transport mechanism in which 2,9-dimethyl-1,10-phenanthroline operates as a carrier for copper ions. The influence of valinomycin on copper uptake indicates that the transmembrane potential is not the driving force in the carrier process.
