Kurzbeschreibung (Abstract)
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.
