Archaea Sulfolobus Cell envelope Proteome
要旨:
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.
