"Electrons flow from the C-terminal reductase domain of one NOS monomer to the N-terminal oxygenase domain of the other NOS monomer (Siddhanta et al., 1998). The primary mode of enzyme activation is the binding of calcium-bound calmodulin to the N-terminal CaM-binding domain. This facilitates a structure change and the flow of electrons from NADPH through the flavins to the oxygenase domain of the other eNOS monomer"
