This works studies a quasilinear, reaction-diffusion type parabolic free boundary problem modelling population dynamics. Hlder norm 谩 priori estimates are established for the free boundary and the solution. Uniqueness of the solution is shown and qualitative properties of the solution are investigated....
Determining the factors that affect the rate, or kinetics, of an enzyme is critical to understanding how that enzyme's function and potential for use. This chapter explains the theoretical basis for the determination of the steady﹕tate kinetic parameters of enzymes, a common experimental objective...
摘要: Classical enzyme kinetics, as developed in the 20th century, had as a primary objective the elucidation of the mechanism of enzyme catalysis. In systems biology, however, the precise mechanism of an enzyme is less important; what is required is a...
In the case of G13D, this result may be explained by the high nucleotide exchange rate measured for this mutant12,35,36. In the cases of the Q61 mutants, earlier reports have noted similar discrepancies; a GDP-state-specific degrader was able to target KRAS(Q61H) in cells26, and KRAS...
Create a Rate Rule for an Exponential Rate of Change Copy CodeCopy Command This example shows how to change the amount of a species similar to a first-order reaction using the first-order rate rule. For example, suppose the speciesxdecays exponentially. The rate of change of speciesxis: ...
CoA biosynthesis7. The eukaryotic PanKs are considered to be the rate-limiting enzymes in CoA biosynthesis and their activities are allosterically regulated by acyl-CoA and CoA8,9. There are four active eukaryotic PanKs: PanK1α and PanK1β, which are encoded by two spliced forms of thePAN...

The number of reactions includes SBML "rate rules", since some models only use rate rules. The graph illustrates that not only has the number of models increased approximately ten-fold since 2005, but the average complexity of those models has nearly tripled in the same period. Full size ...
The larger and less selective OEP24 pore is abundant in C4 plants, in which a higher rate of carbon fixation and metabolite flux occurs13. By contrast, the outward-rectifying OEP21 channel is more prominent in C3 plants and has been shown to interact with ATP, TPs and phosphate in a ...
