Archaeal surface structures. (A) Tetrathionate hydrolase from A. hospitalis YS8 assembles into zipper-like particles on the cell surface. Image reproduced with permission from Krupovic et al. (2012). (B) Electron micrographs of M. maripaludis cells expressing type IV pilus-like structures. Arrows indicate EppA-processed pili, while additional, thicker structures, are PibD-processed flagella. Samples were negatively stained with 2% phosphotungstic acid. Image reproduced with permission from (VanDyke et al., 2008). (C) Non-type IV Mth60 fimbriae of planktonic M. thermoautotrophicus cells by staining with AlexaFluor®488 (Thoma et al., 2008). Image courtesy of R. Wirth, University of Regensburg, Germany. (D) Secreted halomucin complexes (stained green with specific antibody coupled to fluorescein) surrounds quadratic Haloarcula marismortui cell (stained red by Nile blue for polyhydroxy butyrate).
