Molecular Basis of Bacterial Outer Membrane Permeability Revisited

Open access
Nikaido, Hiroshi·2003·Microbiology and Molecular Biology Reviews

Abstract

SUMMARY: Gram-negative bacteria characteristically are surrounded by an additional membrane layer, the outer membrane. Although outer membrane components often play important roles in the interaction of symbiotic or pathogenic bacteria with their host organisms, the major role of this membrane must usually be to serve as a permeability barrier to prevent the entry of noxious compounds and at the same time to allow the influx of nutrient molecules. This review summarizes the development in the field since our previous review (H. Nikaido and M. Vaara, Microbiol. Rev. 49:1-32, 1985) was published. With the discovery of protein channels, structural knowledge enables us to understand in molecular detail how porins, specific channels, TonB-linked receptors, and other proteins function. We are now beginning to see how the export of large proteins occurs across the outer membrane. With our knowledge of the lipopolysaccharide-phospholipid asymmetric bilayer of the outer membrane, we are finally beginning to understand how this bilayer can retard the entry of lipophilic compounds, owing to our increasing knowledge about the chemistry of lipopolysaccharide from diverse organisms and the way in which lipopolysaccharide structure is modified by environmental conditions.

  • Among the best-characterized porins, the three major E. coli proteins OmpF, OmpC and PhoE and the P. aeruginosa OprD are classical examples of porin-mediated antibiotic resistance.

    “Among the best-characterized porins, the three major proteins produced by E. coli (known as OmpF, OmpC and PhoE) and the P. aeruginosa OprD (also known as protein D2) are classical examples of porin-mediated antibiotic resistance.”

    From Mechanisms of Antibiotic Resistance (2016) · cites this paper as [39]

  • Changes in permeability through porin alteration mechanisms frequently result in low-level resistance and are often associated with other resistance mechanisms such as increased efflux pump expression.

    “Importantly, changes in permeability through any of these mechanisms frequently result in low-level resistance and are often associated with other mechanisms of resistance, such as increased expression of efflux pumps (see below) (39).”

    From Mechanisms of Antibiotic Resistance (2016) · cites this paper as [39]

  • Alterations of porins can be achieved by three general processes: a shift in the type of porins expressed, a change in the level of porin expression, and impairment of porin function.

    “Alterations of porins could be achieved by 3 general processes, i) a shift in the type of porins expressed, ii) a change in the level of porin expression, and iii) impairment of the porin function.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
