  • The catechol intermediate is further metabolized through reactions catalyzed by an extradiol dioxygenase, a hydrolase, a hydratase, and an aldolase, respectively ( 3 , 24 , 25 ). (asm.org)
  • 2. Role of oxygen in the metabolic regulation : Besides the well known … More role of oxygen in the energy metabolism, oxygen has been shown to play an important physiological role in metabolic regulation through oxygenase-catalyzed reactions. (nii.ac.jp)
  • Though experimentally determined transport rates of these energy sources are not yet available, we will do a preliminary analysis of the response to catechol uptake by investigating different points on the predicted metabolic landscape. (igem.org)
  • The predicted optimal uptake of catechol through FBA of the E. coli metabolic model is 2.52 mmol/gDW/h, resulting in a growth rate of 0.744 h-1. (igem.org)
  • This is a prediction of the optimal catechol input into the metabolic system in order to produce the maximum amount of biomass components, taking into account the steady-state balancing of all associated metabolic compounds and cofactors. (igem.org)
  • Though prediction of metabolic flux and microbial growth rate has been shown to be generally accurate through this method, experimental usage of catechol may be significantly higher or lower than the purely stoichiometric prediction. (igem.org)
  • This is because the input of catechol into the metabolic network in vivo may trigger metabolic regulation at the expense of the assumed cellular objective (biomass production). (igem.org)
  • Furthermore, even at a given combination of glucose and catechol uptake rate, there is a degree of variability associated with the in silico prediction of internal metabolic fluxes. (igem.org)
