Abstract

The temperature-sensitive Escherichia coli mutant ecfts metC (Lieberman and Hong, 1974), previously shown to be defective in the coupling of metabolic energy to active transport, is also altered in a wide variety of cellular activities at the nonpermissive temperature. These alterations include a lowering of intracellular adenosine 5'-triphosphate levels, an alteration of glucose metabolism such that large quantities of pyruvate and dihydroxyacetone phosphate are excreted into the medium, excretion of accumulated potassium ions, and a cessation of deoxyribonucleic acid, ribonucleic acid, and phospholipid synthesis. Since these effects closely mimic the action of colicins E1 and K on E. coli cells, the possibility that the ecf gene product is the primary biochemical target for these colicins is discussed.
