Xenopus tropicalis Xenopus tropicalis
Xenopus tropicalis: Xenopus tropicalis (The western clawed frog) is a species of frog in the family Pipidae, also known as tropical clawed frog. It is the only species in the genus Xenopus to have a diploid genome. Its genome has been sequenced, making it a significant model organism for genetics that complements the related species Xenopus laevis (the African clawed frog), a widely used vertebrate model for developmental biology. X. tropicalis also has a number of advantages over X. laevis in research, such as a much shorter generation time (<5 months), smaller size (4–6 cm (1.6–2.4 in) body length), and a larger number of eggs per spawn.
It is found in Benin, Burkina Faso, Cameroon, Ivory Coast, Equatorial Guinea, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Nigeria, Senegal, Sierra Leone, Togo, and possibly Mali. Its natural habitats are subtropical or tropical moist lowland forests, moist savanna, rivers, intermittent rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, rural gardens, heavily degraded former forests, water storage areas, ponds, aquaculture ponds, and canals and ditches, KEGG code: xtr.
KEGG directly offers 245 metabolic modules. A module in KEGG is a functional unit of reactions in metabolic pathways that form a chain or chain-like shape. Each module has one or a few inputs or outputs and its intermediate steps do not contain significant in-/out-branches. Thus, the KEGG modules naturally form a genome scale metabolic network. Compared to the M171 network, the KEGG module network omits more branches and contains multiple disconnected subnetworks. When building species specific networks, we first took the modules that are present in the species, identified the subnetworks formed by the modules and removed single modules. Single modules are excluded from FLUXestimator analysis.
The KEGG-module formed genome-wide metabolic map of Xenopus tropicalis is formed by 94 modules, including 10 sub-networks, 502 metabolic genes and 126 intermediate metabolites. The figure below illustrates the reconstructed network. Complete information of the reconstructed network is available in the downloads.
