Ferredoxin (Fd) is surface active; both its area/molecule, A, and surface potential, ΔV, (at an air-water interface) vary with the pH of the subphase. From the surface isotherms (at pH 7.7) A and ΔV are 167 A2 and 170 ± 20 mV, respectively, when the surface tension is 10 dyne/cm.Fd and chlorophyll a (Chl) appear to form a mixed monomolecular film. At pH 7.7 a maximum interaction between Fd and Chl is observed when the monolayer contains a mole ratio of Fd/Chl ≅ 2. Irradiaion of Chl-Fd films, in nitrogen atmosphere, results in a bleaching of Chl and an increase of ΔV. The quantum yield for this bleaching is estimated to be 0.4.
