Mutations in the major gas vesicle protein GvpA and impacts on gas vesicle formation in Haloferax volcanii [PDF]
Molecular Microbiology, 2017 SummaryGas vesicles are proteinaceous, gas‐filled nanostructures produced by some bacteria and archaea. The hydrophobic major structural protein GvpA forms the ribbed gas vesicle wall. An in‐silico 3D‐model of GvpA of the predicted coil‐α1‐β1‐β2‐α2‐coil structure is available and implies that the two β‐chains constitute the hydrophobic interior surface

Analysis of Halobacterium halobium Gas Vesicles [PDF]
Journal of Bacteriology, 1973 Gas vesicles, isolated from lysed Halobacterium halobium cells, gave an amino acid analysis which accounted for 78% of the weight, and the balance was mainly salt and water. One percent of tightly bound d -galactose was found, as well as 2% of phosphate that was not released by treatment ...

Membranes, 2021 Outer membrane vesicles carrying β-lactamase (βLOMVs) protect bacteria against β-lactam antibiotics under experimental conditions, but their protective role during a patient’s treatment leading to the therapy failure is unknown.

Spontaneous mutations in gas vesicle genes ofPlanktothrixspp. affect gas vesicle production and critical pressure [PDF]
FEMS Microbiology Letters, 2002 Wild-type strains of the cyanobacterium Planktothrix rubescens have a cluster of gas vesicle (gvp) genes with repeats of alternating gvpA and gvpC. The gvpC occurs in three length variants, all with the same 3'-sequence, OmegaC. Spontaneous non-buoyant mutants had lost some of the alternating gvpAC copies and their gvpC genes had a novel 3'-end ...

Lipidomic analysis of extracellular vesicles from the pathogenic phase of Paracoccidioides brasiliensis. [PDF]
PLoS ONE, 2012 Fungal extracellular vesicles are able to cross the cell wall and transport molecules that help in nutrient acquisition, cell defense, and modulation of the host defense machinery.Here we present a detailed lipidomic analysis of extracellular vesicles ...

Microbiology, 1988 Summary: The gas vesicles of the cyanobacteria Anabaena flos-aquae and Microcystis sp. contain, in addition to the principal M r 7400 gas vesicle protein GVPa, a second, M r 22000 protein component, GVPc. We show here that GVPc can be removed from the gas vesicles, without their collapsing, by rinsing in solutions of sodium dodecyl sulphate.

Permeability of Gas Vesicles to Perfluorocyclobutane [PDF]
Microbiology, 1982 SUMMARY: The permeability of intact gas vesicles, isolated from the cyanobacterium Anabaena flos-aquae, to percyclofluorobutane (C4F8), has been investigated by two methods. Warburg manometry showed that a suspension of intact gas vesicles exchanges more C4F8 than an equivalent suspension of collapsed ones.
