Metabolite concentrations, fluxes and free energies imply efficient enzyme usage. [PDF]
, 2016 In metabolism, available free energy is limited and must be divided across pathway steps to maintain a negative ΔG throughout. For each reaction, ΔG is log proportional both to a concentration ratio (reaction quotient to equilibrium constant) and to a ...

Unraveling thioredoxin-linked metabolic processes of cereal starchy endosperm using proteomics [PDF]
, 2003 Application of a thiol-specific probe, monobromobimane, with proteomics and enzyme assays led to the identification of 23 thioredoxin targets in the starchy endosperm of mature wheat seeds (Triticum aestivum cv. Butte), almost all containing at least two

Fructose metabolism in Chromohalobacter salexigens: interplay between the Embden–Meyerhof–Parnas and Entner–Doudoroff pathways [PDF]
, 2019 Background The halophilic bacterium Chromohalobacter salexigens metabolizes glucose exclusively through the Entner–Doudoroff (ED) pathway, an adaptation which results in inefficient growth, with significant carbon overflow, especially at low salinity ...

The heat released during catalytic turnover enhances the diffusion of an enzyme [PDF]
, 2014 Recent studies have shown that the diffusivity of enzymes increases in a substrate-dependent manner during catalysis,. Although this observation has been reported and characterized for several different systems–, the precise origin of this phenomenon is ...

pH-dependence of the triose phosphate isomerase reaction [PDF]
Biochemical Journal, 1972 The pH-dependences of the kinetic parameters kcat. and Km for the triose phosphate isomerase reaction were determined in each direction. Apparent pKa values of 6.0 and 9.0 are observed in the dependences of kcat./Km. The pH-dependences of kcat. are sigmoid, with apparent pKa values of about 6.0.

Artificial Photosynthesis Would Unify the Electricity-Carbohydrate-Hydrogen Cycle for Sustainability [PDF]
, 2010 Sustainable development requires balanced integration of four basic human needs – air (O2/CO2), water, food, and energy. To solve key challenges, such as CO2 fixation, electricity storage, food production, transportation fuel production, water ...
