Comparison of S. solfataricus grown on l-fucose and d-glucose

e:Bio - Innovations Competition Systems Biology

Within the e:Bio - Innovationswettbewerb Systembiologie (Federal Ministry of Education and Research (BMBF)), the SulfoSYSBIOTECH consortium (10 partners), aim to unravel the complexity and regulation of the carbon metabolic network of the thermoacidophilic archaeon Sulfolobus solfataricus (optimal growth at 80°C and pH 3) in order to provide new catalysts ‘extremozymes’ for utilization in White Biotechnology.

Based on the available S. solfataricus genome scale metabolic model (Ulas et al., 2012) ...

Integrated systems biology approach including transcriptome, metabolome, biochemistry, proteome analyses and modelling to elucidate the catabolic pathway for L-fucose in S. solfataricus P2.

Genome scale metabolic model of Sulfolobus solfataricus specific scenario: modelling of L-fucose degradation pathways

RNAseq analysis of S. solfataricus grown on either L-fucose or D-glucose

Activity assays in cell free extracts of S. solfataricus grown on either L-fucose or D-glucose and activity assays with recombinant proteins

Comparative GC-MS based metabolomics of S. solfataricus growing on either L-fucose or D-glucose. CoA derivatives were analysed via HPLC-MS

Comparative proteomics of S. solfatricus grown on either L-fucose or D-glucose.

Metabolic model of Sulfolobus solfataricus P2 in the SBML (xml) and metano (txt, sce, fba) format. Scenarios are specific for growth on D-glucose or L-fucose as sole carbon source. Different theoretical routes of L-fucose degradation were modeled (E. coli-like, Xanthomonas-like and lactaldehyde-forming). Highest overall agreement between the model and experimental data was observed for the lactaldehyde-forming route.
