Studies

To investigate phenol degradation in Saccharolobus solfataricus transcriptome and metabolome analyses were performed with cells grown on phenol as sole carbon source. Cells grown on D-glucose served as reference. Metabolic modelling was used to compare efficiency of phenol utilization in terms of oxygen demand and energy yield with the reference condition.

To investigate amino acid degradation pathways in Sulfolobus solfataricus transcriptome, proteome and metabolome analyses were performed on cells grown on caseinhydrolysate as carbon source. Cells grown with glucose served as reference condition. Metabolic modelling was used to compare the efficiency of different degradation routes.

PGK-GAPDH reactions were studied in vitro at 30 and 70 using yeast or Sso enzymes

PGK reaction at 30 C. Yeast PGK was incubated at 30 C, in the presence or absence of the ATP recycling system, and the conversion of 3 PG to BPG was followed. SED-ML simulations Fig. 1A: https://jjj.bio.vu.nl/models/experiments/kouril2017_fig1a/simulate

PGK reaction at 70C. Sulfolobus solfataricus PGK was incubated at 70C in presence and absence of an ATP recycling system. Changes in metabolite concentrations was followed via 31P NMR or enzymatic analyses.

BPG produced with yeast PGK was incubated at 70 C,upon which BPG rapidly dephosphorylates to 3PG. SED-ML: https://jjj.bio.vu.nl/models/experiments/kouril2017_fig2b/simulate
