Incorporation of reaction centers into submitochondrial particles resulting in light induced electron transfer.

Conditions for the incorporation of reaction centers, isolated from Rhodospirillum rubrum, into submitochondrial particles have been studied. Incorporation of the reaction centers into the lipid bilayer occurs in both orientations. Electron flow from the light activated reaction center to the b-c1 complex is demonstrated. Preliminary data on the reaction kinetics of the b cytochromes are given.
