Glycine, Serine and Threonine Metabolism in C. merolae

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


The Cyanidiophyceae, including C. merolae (Cyanidioschyzon merolae), are a basal clade within the red lineage plastids. The red algae are thought to be one of the basal eukaryotic lineages, and may possess ancestral features of eukaryotic phototrophs. C. merolae is the first species of algae to be sequenced; the organism consists of a single cell that has three smaller compartments, each containing DNA. It is a unicellular, obligate photoautotrophic red alga that is found in acidic hot springs. The C. merolae cell contains one mitochondrion, one plastid with a centrally located plastid nucleoid, one Golgi body, and one microbody (Ref.1). The major biological processes of C. merolae are dependant on its plastid genome. The striking feature of this genome is [...]
