Function and biosynthesis of gas vesicles in halophilicArchaea
Copyright policy )Function and biosynthesis of gas vesicles in halophilicArchaea
The proteinaceous gas vesicles produced by various microorganisms including halophilic Archaea are hollow, gas-filled structures with a hydrophobic inner and a hydrophilic outer surface. The structural components of gas vesicles and their biosynthesis are still under investigation; an 8-kDa polypeptide appears to be the major constituent of the gas-vesicle envelope. Genetic analysis of the halobacterial gas-vesicle synthesis revealed an unexpected complexity: about 14 genes organized in three transcription units are involved in gas-vesicle structure, assembly, and gene regulation. Here we describe the comparison of three different genomic regions encoding gas vesicles in Halobacterium salinarium (p-vac and c-vac regions) and Haloferax mediterranei (mc-vac region) and speculate on the function of the gene products involved in gas-vesicle synthesis.
