A novel aspect of the inhibition by arsenicals of binding-protein-dependent galactose transport in gram-negative bacteria.

Abstract

The inhibitory effects of arsenate and arsenite on binding-protein-dependent transport systems are reconsidered. It is shown that arsenate inhibits binding-protein-dependent galactose transport in proteoliposomes energized either by dihydrolipoamide and NAD+ or by a membrane potential (under conditions where ATP metabolism is not implicated); this result is… (More)
