Based on initial cell material, series of SOPs connected with assays of enzymes involved in Central Carbon Metabolism of S. solfataricus have been developed.

Samples obtained form the central fermentation facility of Sulfosys have been compared using iTRAQ (isobaric tag for relative and absolute quantification). A pilot experiment resulted in creation of SOP and initial data on cells grown at 70 and 80C

In order to get uniform data from all geographically separated partners in a consortium, central fermentation facility has been set-up. Based on empirical data, standard procedures for growing S. solfataricus cells have been developed.

Pilot experiment concerning metabolome of S. solfataricus was conducted in order to acquire SOPs regarding the technique and gain insight on differences in metabolite concentrations at 70 and 80C

The pilot experiment was conducted in order to create SOPs and to gain insight in transcriptome of cells grown at 70 and 80C

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

PGK model for S. solfataricus

PGK-GAPDH model Sulfolobus kouril8

PGK 70C SBML

Metabolic model of Sulfolobus solfataricus P2 in the SBML (sbml) and metano (txt, sce, fba) format. Scenarios are specific for growth on D-glucose or caseinhydrolysate as sole carbon source.

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.

Model of reconstituted gluconeogenesis system in S. solfataricus based on the individual kinetic models for PGK, GAPDH, TPI, FBPAase.

Exponential decay model of gluconeogenic intermediates

Mathematical model for TPI kinetics, GAP and DHAP saturation, and inhibition with 3PG and PEP.

Mathematical model for GAPDH kinetics, BPG, NADPH, NADP, GAP and Pi saturation.

Mathematical model for FBPAase kinetics, saturation with DHAP and GAP

Mathematical model for PGK kinetics, ADP, ATP, 3PG and BPG saturation.

The model describes the Entner-Doudoroff pathway in Sulfolobus solfataricus under temperature variation. The package contains source code written in FORTRAN as well as binaries for Mac OSX, Linux, and Windows. If compiling from source code, a FORTRAN compiler is required.
