Transport of iron across the outer membrane.

Biology of metals - 1 Jan 1991

Braun V, Günter K, Hantke K

Abstract excerpt

The TonB protein is involved in energ-coupled receptor-dependent transport processes across the outer membrane. The TonB protein is anchored in the cytoplasmic membrane but exposed to the periplasmic space. To fulfill its function, it has to couple the energy-providing metabolism in the cytoplasmic membrane with regulation of outer membrane receptor activity. Ferrichrome and albomycin transport, uptake of colicin...
