Figure 8. Proposed schematic diagram of the D. radioduranscell envelope, adapted from previous reports11,28,31,36,37.
(a) Wild type strain. (b) DR_146T knockout strain. The TAM complex containing the DR_146T and an unknown cooperating protein was indicated by dashed box. In wild type cells, the S-layer assembles properly and acts as a scaffold for the cell envelope. In the DR_146T mutant, SlpA (DR_2577) is present as fragments in the peeling cell envelope. Components in the carbohydrate coat, outer membrane and periplasm dissociate from the cell.
