TABLE 3.
C. jejuni homologues of PSTC proteins
| Class | C. jejuni protein | Class characteristics | B. subtilis protein |
|---|---|---|---|
| I | CtsE | Walker A box | ComGA |
| II | CtsF | Membrane protein | ComGB |
| III | CtsG CtsT Cj107a | Conserved N-terminal sequence resembling cleavage sites of type IV prepilin proteins | ComGC ComGD ComGe ComGG |
| IV | Cj0825b | Prepilin peptidase | ComC |
| V | CtsD | Secretin | Not present |
a
Cj1078 has not yet been demonstrated to play a role in transformation in C. jejuni. It is downstream of CtsT, which also has a putative prepilin peptidase cleavage site.
b
Cj0825 has been described as having a role in transformation by Wilson et al. (Abstr. 103rd Gen. Meet. Am. Soc. Microbiol.)
