Reconstruction of extended Petri nets from time series data and its application to signal transduction and to gene regulatory networks

Table 2 Modeled molecular events that, starting from the initial marking, lead to successive states of the Petri net

Process	leads to State
Initial marking, inorganic phosphate present	x0
Uptake of Pi, depleting Pi from the periplasm	x1
Dephosphorylation of PstSCAB-P	x2
Activation of PhoU	x3
Phosphorylation of PhoR	x4
Phosphorylation of PhoB	x5
Biosynthesis of PhoA	x6
Transport of PhoA into the periplasm	x7
Degradation of Po_PP (organic phosphate)	x8
Phosphorylation of PstSCAB	x9
Deactivation of PhoU	x10
Dephosphorylation of PhoB-P	x11

The table is useful to assign the state vectors listed in Tables 3 and 4 to the subsequently occurring molecular events.
