Imported:YPM/Fus3 Kss1 preference PO4 factor
<modelParameter>Fus3_Kss1_preference_PO4_factor = </modelParameter>
This is the factor by which Fus3 is more readily phosphorylated by active Ste7 than Kss1 is.
kcat_Ste7ppKss1_PO4 = kcat_Ste5Ste7ppFus3_PO4 / Fus3_Kss1_preference_PO4_factor
Fus3_Kss1_preference_PO4_factor > 1 means that Fus3 is more strongly phosphorylated than Kss1.
See MAPK_phosphorylation_cascade for more details.
