Transmembrane ferricyanide reductase activity in Ehrlich ascites tumor cells.

Abstract

A transmembrane ferricyanide reductase activity was assayed in intact Ehrlich ascites tumor cells. Kinetic measurements gave a Km of 0.14 mM and a Vmax of 0.31 mumol/min per 10(6) cells. In short-term batch experiments, this activity was enhanced in the presence of 10 mM lactate, a source of cytosolic NADH. The transmembrane redox activity was accompanied… (More)
