Gains and losses of cellular functions in T. kodakaraensis when compared to Pyrococcus spp.
Gains |
| Improved α-polysaccharide degradationa |
| Chitin degradationa |
| Additional pyruvate oxidation |
| Tyr biosynthesis |
| His biosynthesisa |
| Riboflavin biosynthesisa |
| Deoxyribose metabolism |
| Thymidine salvage |
| Additional cation transporters (Fe2+, Fe3+, Mo2+, K+, Na+) |
| Improved stress response system (especially for cold adaptation?) |
| Losses |
| Ile, Val, and Leu biosynthesisb |
| Thlamine biosynthesis (partially) |
| Others |
| Distinct restriction system |
