This finding suggests that these substrates may be essential carbon sources for these bacteria and provides useful clues for future development of culture media for Spiroplasma.
Trypanosoma cruzi, the etiological agent of Chagas disease, uses proline as its main carbon source, essential for parasite growth and stage differentiation in epimastigotes and amastigotes.
iRY1243 showed good performance when predicting the cell growth physiological parameters, the growth capability on the reported carbon and nitrogen sources, the metabolic flux distribution with labeled glucose as the sole carbon source, the essential and partially essential genes, and the effects of gene deletion or overexpression on cell growth and S-adenosyl-l-methionine production.
iRY1243 showed good performances when predicting the growth capability on most of the reported carbon and nitrogen sources, the metabolic flux distribution with glucose as a sole carbon source, the essential and partially essential genes, and the effects of gene deletion or overexpression on cell growth and S-adenosyl-l-methionine production.
The other two enzymes were 4-alpha-glucanotransferase (2.4.1.25) and amylo-alpha-1,6-glucosidase (3.2.1.33), which constitute the glycogen debranching system (GDB1), essential for glycogen utilization as carbon source [ 67].
In the current work we present the first extensively curated metabolic network reconstruction for C. difficile (strain 630) iMLTC806cdf and validate it with experimental data on essential metabolites and carbon sources.
They determine the supply of the organic carbon source (electron donor) essential for denitrification.
Tps1 is essential for growth on rapid fermentative carbon source as used in this study, and therefore a gene expression profile of tps1Δ could not be determined.
Photosynthetic reactions are thus essential not only in providing a carbon source but also in generating reducing power (NADH and NADPH) and energy (ATP) for fatty acid synthesis [ 26].
The root nodule is essential to provide rhizobia with both a carbon source and an appropriate cellular environment allowing the bacterial nitrogenase to fix atmospheric nitrogen.
