EI of the Phosphotransferase System of Escherichia coli: Mathematical Modeling Approach to Analysis of Its Kinetic Properties
Dependence of the steady state HPr phosphorylation rate on the PEP and Pyr concentrations (contour maps) calculated by the Model II. (a) total stationary rate of HPr phosphorylation. Also shown contributions (to the total HPr phosphorylation rate) of rates of the HPr phosphorylation: (b) by the monomer; (c) by the doubly phosphorylated dimer; (d) by the singly phosphorylated dimmer Concentrations of the enzymes are close to physiological ones (taken from ), which are: EI = 5 μM, HPr = 40 μM.
