Abstract
The pore properties of PhoE protein channels in the outer membrane of a lipoprotein-deficient mutant and in
a mutant with heptose-deficient lipopolysaecharide were investigated. The absence of lipoprotein neither
affects the rate of permeation of glucose 6-phosphate or of the β-lactam antibiotic eephsulodin through the
PhoE pore nor the inhibition of cephsulodin permeation
