Mechanisms of TonB-catalyzed iron transport through the enteric bacterial cell envelope

P E Klebba et al. J Bioenerg Biomembr. 1993 Dec.

Abstract

The recent solution of enteric bacterial porin structure, and new insights into the mechanism by which outer membrane receptor proteins recognize and internalize specific ligands, advocates the re-evaluation of TonB-dependent transport physiology. In this minireview we discuss the potential structural features of siderophore receptors and TonB, and use this analysis to evaluate both existing and new models of energy and signal transduction from the inner membrane to the outer membrane of gram-negative bacteria.
