Gram-negative bacteria developed a number of tools to avoid accumulation of cell-toxic
compounds. The outer membrane as a first defense system is tightly packed reducing …

The recent discovery of binding protein dependent secondary transporters and the ever-
growing family of membrane potential generating secondary transporters emphasize the …

Bacteria can be subdivided on the basis of the structure of the cell envelope into Gram-
negative and Gram-positive. The cell envelope of Gram-negative bacteria is composed of a …

Publisher Summary This chapter explains some of the recent developments regarding the
role of the P-transferase system in sugar transport, particularly as studied in isolated …

Using a 10cm flow-through cuvette in a high precision spectrophotometer linked to a mini-
computer, the growth rate dependence of Escherichia coli on glucose concentration has …

Pseudomonas aeruginosa is usually resistant to a wide variety of antibacterial agents, and it
has been inferred, on the basis of indirect evidence, that this was due to the low permeability …

Publisher Summary This chapter discusses the uptake of solutes through bacterial outer
membranes. The cell envelope of Gram-negative bacteria consists of three different layers …

In recent years it has become evident that transport processes across membranes play a
crucial role in many metabolic systems. The activities of these transport processes often …

Diffusion of small molecules across the outer membrane of gram-negative bacteria may
occur through protein channels and through lipid bilayer domains. Among protein channels …
