Gas vesicle protein GvpL/GvpF (IPR009430)

Short name: Gas-vesicle_GvpL/GvpF

Overlapping homologous superfamilies


Family relationships



Gas vesicles provide cells with buoyancy, enabling them to remain at the water surface. These organelles are generally synthesized by halophilic archaea and cyanobacteria, as well as some other prokaryotes. A cluster of 12-14 gvp genes (gvpMLKJIHGFEDACNO) is responsible for gas vesicle synthesis in Halobacterium sp. [PMID: 15126480]. GvpF and GvpL are essential for gas vesicle formation and display sequence similarity to one another, both containing predicted coiled-coil domains that are often involved in self-oligomerisation; and are structural components of the vesicle [PMID: 15126480].
