Influence of regulatory strength (k r,1).(A) Initial enzyme concentrations for the different values of the regulatory constant k r,1 (B) Regulatory efforts (r e g i ) for different values of k r,1. Please note the logarithmic scale of the x-axis. The dashed line indicates the value of the inhibitory constant k r,1 at which transcriptional regulation is switching from a sole regulation of the terminal enzyme to a regulation of initial and terminal enzyme.
