title: Outer membranes of gram-negative bacteria. XV. Transmembrane diffusion rates in lipoprotein-deficient mutants of Escherichia coli.
abstract: Permeability of the outer membrane to 6-aminopenicillanic acid was unaltered in an lpo mutant, lacking the Braun lipoprotein, a result suggesting that the lipoproteins by themselves form no or few diffusion pores.
