Comparison of replacements among bacteria with pepsin homologues
| Family |
Shewanella amazonensis |
Shewanella loihica |
Shewanella sediminis |
Colwellia psychrerythraea |
Sinorhizobium medicae |
Marinomonas sp. MWYL1 |
| A1 (pepsin) | 55.5 | 42.4 | 43.6 | 41.3 | 17.1 | 15.5 |
| A8 (signal peptidase 2) | 70.8 | 72.4 | 67.6 | 48.3 | 35.8 | 46.4 |
| S16 (endpeptidase Clp) | 89.0 | 90.9 | 89.9 | 78.1 | 61.6 | 67.2 |
The protein sequences from Shewanella denitrificans were compared with orthologous protein sequences from other bacteria. Sequences were aligned with Muscle [30] and percentage identities calculated using Alistat http://hmmer.janelia.org/.
