Distribution of CarDNter-like proteins among bacteria and comparison with CdnL
| Taxonomical group | Length (number of residues) | Identity to CdnL (%) | Similarity to CdnL (%) |
|---|---|---|---|
| δ-Proteobacteria | 125–188 | 33–100 | 55–100 |
| α-Proteobacteria | 143–456 | 27–39 | 49–59 |
| Actinobacteria | 137–301 | 24–39 | 47–68 |
| Firmicutes | 148–176 | 24–47 | 47–70 |
| Deinococcus-Thermus | 145–178 | 24–30 | 44–54 |
| Spirochaetales | 161–208 | 26–37 | 50–64 |
| Bacteroidetes | 158 | 36 | 61 |
A total of 449 members were found in a BLAST search analysis of the 3179 bacterial genomes available at http://www.ncbi.nlm.nih.gov (complete—912, assembly—1127, unfinished—1140) using CdnL as query. Genomes of β-, ε- and γ-Proteobacteria, Chlamydiae and Cyanobacteria lack CarDNter-like proteins.
