Haloarchaea and the formation of gas vesicles. [PDF]
Life (Basel), 2015 Halophilic Archaea (Haloarchaea) thrive in salterns containing sodium chloride concentrations up to saturation. Many Haloarchaea possess genes encoding gas vesicles, but only a few species, such as Halobacterium salinarum and Haloferax mediterranei ...

Molecular genetic and physical analysis of gas vesicles in buoyant enterobacteria. [PDF]
Environ Microbiol, 2016 Different modes of bacterial taxis play important roles in environmental adaptation, survival, colonization and dissemination of disease. One mode of taxis is flotation due to the production of gas vesicles.

Advances in the application of gas vesicles in medical imaging and disease treatment. [PDF]
J Biol EngThe gas vesicle (GV) is like a hollow nanoparticle consisting of an internal gas and a protein shell, which mainly consists of hydrophobic gas vesicle protein A (GvpA) and GvpC attached to the surface.

A computed tomography observation of the Unzen lava reveals the frequent existence of vesicles and crystals in proximity. [PDF]
Sci RepVolcanic outgassing through interconnected bubble networks controls eruption dynamics. Frameworks formed by crystals may facilitate gas escape, but the relative spatial arrangements of bubbles and crystals remain overlooked. We conducted multi-resolution

Measuring gas vesicle dimensions by electron microscopy [PDF]
Protein Science, 2021 Abstract Gas vesicles (GVs) are cylindrical or spindle‐shaped protein nanostructures filled with air and used for flotation by various cyanobacteria, heterotrophic bacteria, and Archaea. Recently, GVs have gained interest in biotechnology applications due to their ability to serve as imaging agents and actuators for ultrasound ...

Gas vesicle formation in halophilic Archaea [PDF]
Archives of Microbiology, 1997 Gas vesicles are intracellular, microbial flotation devices that consist of mainly one protein, GvpA. The formation of halobacterial gas vesicles occurs along a complex pathway involving 14 different gvp genes that are clustered in a genomic region termed the "vac region".

Biochemical Journal, 1989 One of the most extraordinary structures found in bacteria is the gas vesicle. It has the form of a shell of protein molecules enclosing a gas-filled space. The properties of this structure ― its rigidity, its contrasting inner and outer surfaces, its permeability to gases and impermeability to liquid water ― are all provided by its constituent ...

Gas vesicle protein expression for reconstitution of synthetic gas vesicles in yeast [PDF]
, 2021 Given the potential applications of gas vesicles (GVs) in multiple fields including antigen-displaying and imaging, heterologous reconstitution of synthetic GVs is an attractive and interesting study that has translational potential. Here, we attempted to express and assemble GV proteins (GVPs) into GVs using the model eukaryotic organism Saccharomyces
