Abstract
The crenarchaea Sulfolobus acidocaldarius, S. solfataricus and S. tokodaii, release membrane vesicles into the medium. These membrane vesicles consist of tetraether lipids and are coated with an S-layer. A proteomic analysis reveals the presence of proteins homologous to subunits of the eukaryotic endosomal sorting complex required for transport (ESCRT). Immunodetection of one of these homologs suggest a cell surface localization in intact cells. These data suggest that the membrane vesicles in Sulfolobus sp. emerge from a specific budding process with similarity to the endosomal sorting pathway.Entities:
