Description
Pathway control factors, PCF, are flux control factors, expressing the relative change of flux in response to a transition between two Electron-transfer-pathway states due to a change of (i) substrate availability or (ii) inhibition of enzyme steps in the pathway, in a defined coupling-control state.
Abbreviation: PCF

From substrate to pathway control factor
- Previous terminology: Substrate control factors, SCF, are flux control factors, expressing the relative change of flux in response to a transition of substrate availability in a defined coupling-control state.
- Substrate control factors, therefore, are a subgroup of pathway control factors.
