The corynebacterial cell envelope. A schematic representation of the general envelope structure of corynebacteria is shown. The different layers are found in almost all species, and distribution of single components like lipomannan (LM) and lipoarabinomannan (LAM) might differ (for details, see text). Porin proteins might also be present in top layer, S-layer, and pili proteins not shown (figure courtesy of S. Morbach, Friedrich-Alexander-Universität Erlangen-Nürnberg).
