Gag-Pol Processing during HIV-1 Virion Maturation: A Systems Biology Approach
Figure 8
The rate of change in the concentration of a given fragment Si,j.
Assuming quasi steady state for the enzyme-substrate complexes, , the rate of change consists of loss by cleavage at any of the internal cleavage sites, and production by “trimming” longer fragments that have an uncleaved site at either terminus.
