ferredoxin:SiR complex formation and interprotein affinity are thermodynamically adjusted by both enthalpy and entropy through electrostatic and non-electrostatic interactions. A combination of electrostatic and non-electrostatic forces stabilizes the complex with similar interfaces and modulates the binding affinity and mode
