The genome of M. maripaludis consists of 1,661,137 bp and has been sequenced, leading to the identification of over 1,700 protein-coding genes.[1]
Metabolism[edit]
The metabolic landscape of M. maripaludis consists of eight major subsystems:
- Amino acid metabolism (Caitlin)
- Glycogen metabolism (Caitlin)
- Glycolysis
- Methanogenesis
- Nitrogen metabolism
- Non-oxidative pentose phosphate pathway
- Nucleotide metabolism
- Reductive citric acid (RTCA) cycle
Cell Structure Notes:
Methanococcus maripaludis is a weakly-motile coccus specie of methanogenic archaea of 0.9–1.3 µm diameters. It grows best in conditions of 20°C and 45°C with a pH of 6.5 to 8.0. [2]
Cell structure[edit]
The cell wall of Methanococcus maripaludis has an S-layer[3] that does not contain peptidoglycan, which helps to identify its domain as Archaea. The S-layer is made of glycoproteins and encloses the whole cell. It protects the cell and is its direct interaction with the environment. The S-layer gives the archaea cell a stabilization barrier being resistant to environmental changes. [3]
Genetic characteristics[edit]
The sequenced genome also revealed about 48 protein transporter systems, largely dominated by ABC transporters followed by iron transporters.[1]

If you're starting a new article, you can develop it here until it's ready to go live. If you're working on improvements to an existing article, copy only one section at a time of the article to this sandbox to work on, and be sure to use an edit summary linking to the article you copied from. Do not copy over the entire article. You can find additional instructions here. Remember to save your work regularly using the "Publish page" button. (It just means 'save'; it will still be in the sandbox.) You can add bold formatting to your additions to differentiate them from existing content. |
