Monoclonal Antibodies Against Bacterial Outer Membrane Antigens
1985Monoclonal antibodies have proved to be highly specific tools for defining the antigenic epitopes of Pseudomonas aeruginosa outer membrane macromolecules. In this article we have highlighted the use of monoclonal antibodies in the study of lipopolysaccharide heterogeneity and in particular have demonstrated that single monoclonal antibodies can ...

Bacterial Nanobioreactors–Directing Enzyme Packaging into Bacterial Outer Membrane Vesicles
ACS Applied Materials & Interfaces, 2015All bacteria shed outer membrane vesicles (OMVs) loaded with a diverse array of small molecules, proteins, and genetic cargo. In this study we sought to hijack the bacterial cell export pathway to simultaneously produce, package, and release an active enzyme, phosphotriesterase (PTE). To accomplish this goal the SpyCatcher/SpyTag (SC/ST) bioconjugation

Porin from Bacterial and Mitochondrial Outer Membrane
Critical Reviews in Biochemistry, 1985The outer membrane of gram-negative bacteria acts as a molecular filter with defined exclusion limit for hydrophilic substances. The exclusion limit is dependent on the type of bacteria and has for enteric bacteria like Escherichia coli and Salmonella typhimurium a value between 600 and 800 Daltons, whereas molecules with molecular weights up to 6000 ...

Proteomics in gram‐negative bacterial outer membrane vesicles
Mass Spectrometry Reviews, 2008AbstractGram‐negative bacteria constitutively secrete outer membrane vesicles (OMVs) into the extracellular milieu. Recent research in this area has revealed that OMVs may act as intercellular communicasomes in polyspecies communities by enhancing bacterial survival and pathogenesis in hosts.

Bacterial ß-Barrel Outer Membrane Proteins
2009ß-barrel outer membrane proteins constitute the second and less well-studied class of transmembrane proteins. They are present exclusively in the outer membrane of Gram-negative bacteria and presumably in the outer membrane of mitochondria and chloroplasts.

Bacterial outer membrane evolution via sporulation?
Nature Chemical Biology, 2011The distinction between different cell-envelope architectures has defined much of our thinking about bacterial systematics, but the evolution of different envelope layers has been harder to understand. A recent publication focused on the non-model organism Acetonema longum provides important clues to the possible origin of the second membrane typical ...

Porins and specific channels of bacterial outer membranes
Molecular Microbiology, 1992SummaryPorins and specific channels both produce water‐filled pores that allow the transmembrane diffusion of small solutes, but the latter contain specific ligandbinding sites within the channels. Recent structural studies show that many or most of these proteins exist as βbarrels with the βstrands traversing the thickness of the outer membrane.

Bacterial bioreactors: Outer membrane vesicles for enzyme encapsulation
2019Bacterial membrane vesicles, whether naturally occurring or engineered for enhanced functionality, have significant potential as tools for bioremediation, enzyme catalysis, and the development of therapeutics such as vaccines and adjuvants. In many instances, the vesicles themselves and the naturally occurring proteins are sufficient to lend ...

General and Specific Porins from Bacterial Outer Membranes
Journal of Structural Biology, 1998Over the past years, the three-dimensional structures of several bacterial porins have been determined to high resolution. Apart from revealing an unusual type of architecture, the hollow beta-barrel, they have made it possible to investigate in detail various structure-function relationships.
