Gas Vesicle Nanoparticles for Antigen Display [PDF]

Vaccines, 2015
Microorganisms like the halophilic archaeon Halobacterium sp. NRC-1 produce gas-filled buoyant organelles, which are easily purified as protein nanoparticles (called gas vesicles or GVNPs). GVNPs are non-toxic, exceptionally stable, bioengineerable, and self-adjuvanting.

Evolution of Phytoplankton in Relation to Their Physiological Traits

Journal of Marine Science and Engineering, 2022
Defining the physiological traits that characterise phytoplankton involves comparison with related organisms in benthic habitats. Comparison of survival time in darkness under natural conditions requires more information.

The sequence of the major gas vesicle protein, GvpA, influences the width and strength of halobacterial gas vesicles [PDF]

FEMS Microbiology Letters, 2002
Transformation experiments with Haloferax volcanii show that the amino acid sequence of the gas vesicle protein GvpA influences the morphology and strength of gas vesicles produced by halophilic archaea. A modified expression vector containing p-gvpA was used to complement a Vac(-) strain of Hfx.

The distribution of the outer gas vesicle protein, GvpC, on the Anabaena gas vesicle, and its ratio to GvpA [PDF]

Journal of General Microbiology, 1993
Previous studies have shown that gas vesicles isolated from the cyanobacterium Anabaena flos-aquae contain two types of protein, GvpA, a small hydrophobic protein that forms the main ribbed structure, and GvpC, a protein comprising five repeats of a 33-amino-acid-residue motif, which is located on the outer surface of the GvpA shell.

Recombinantly Expressed Gas Vesicles as Nanoscale Contrast Agents for Ultrasound and Hyperpolarized MRI. [PDF]

AIChE J, 2018
Ultrasound and hyperpolarized magnetic resonance imaging enable the visualization of biological processes in deep tissues. However, few molecular contrast agents are available to connect these modalities to specific aspects of biological function.

Reshaping Membrane Polymorphism of Polymer Vesicles through Dynamic Gas Exchange

, 2021
The quest for a universal method to shape the vesicular morphology in dynamic and diversified manners is a challenging topic of cell mimicry. Here we present a simple gas exchange strategy that can direct the deformation movements of polymer vesicles ...

The IclR-family transcriptional regulator XyrR controls flotation, motility, antibiotic production and virulence in Serratia sp. ATCC 39006

Frontiers in Microbiology
The opportunistic pathogen Serratia sp. ATCC 39006 (S39006) is a rod-shaped, motile, Gram-negative bacterium that produces a 𝛽-lactam antibiotic (a carbapenem) and a bioactive red-pigmented tripyrrole antibiotic, prodigiosin.
