A Complex Endomembrane System in the Archaeon Ignicoccus hospitalis Tapped by Nanoarchaeum equitans
Based on serial sectioning, focused ion beam scanning electron microscopy (FIB/SEM), and electron tomography, we depict in detail the highly unusual anatomy of the marine hyperthermophilic crenarchaeon, Ignicoccus hospitalis. Our data support a complex and dynamic endomembrane system consisting of cytoplasmic protrusions, and with secretory function. Moreover, we reveal that the cytoplasm of th...
متن کاملThe interaction of Nanoarchaeum equitans with Ignicoccus hospitalis: proteins in the contact site between two cells.
The two archaea Ignicoccus hospitalis and Nanoarchaeum equitans form a unique intimate association, the character of which is not yet fully understood. Electron microscopic investigations show that at least two modes of cell-cell interactions exist: (i) the two cells are interconnected via thin fibres; and (ii) the two cell surfaces are in direct contact with each other. In order to shed furthe...
متن کاملProteomic Characterization of Cellular and Molecular Processes that Enable the Nanoarchaeum equitans-Ignicoccus hospitalis Relationship
Nanoarchaeum equitans, the only cultured representative of the Nanoarchaeota, is dependent on direct physical contact with its host, the hyperthermophile Ignicoccus hospitalis. The molecular mechanisms that enable this relationship are unknown. Using whole-cell proteomics, differences in the relative abundance of >75% of predicted protein-coding genes from both Archaea were measured to identify...
متن کاملHappy together: genomic insights into the unique Nanoarchaeum/Ignicoccus association
The complete genome sequence of the crenarchaeon Ignicoccus hospitalis published recently in Genome Biology provides a great leap forward in the dissection of its unique association with another hyperthermophilic archaeon, Nanoarchaeum equitans.
متن کاملBypassing rRNA methylation by RsmA/Dim1during ribosome maturation in the hyperthermophilic archaeon Nanoarchaeum equitans
In all free-living organisms a late-stage checkpoint in the biogenesis of the small ribosomal subunit involves rRNA modification by an RsmA/Dim1 methyltransferase. The hyperthermophilic archaeon Nanoarchaeum equitans, whose existence is confined to the surface of a second archaeon, Ignicoccus hospitalis, lacks an RsmA/Dim1 homolog. We demonstrate here that the I. hospitalis host possesses the h...
