Figure 8 A diagram of the photos3mthetic apparatus of oxygenic phototrophs, illustrating the proteins that contain iron (Fe) with the potential of electrons at each step superimposed. Abhreviations LHC, hght harvesting complex C)d, c3dochrome b, f with subscripts refer to the spectroscopic type of cytochrome P680, the reaction center of photosystem II (PSII) P700 the reaction center of photosystem I (PSI).

Lam, Ortiz and Malkin further fractionated PSI-200 into the reaction-center core complex containing -100 chlorophyll molecules per P700, calling it PSI-KX), and the hght-harvesting chlorophyll-protein complex LHC I, as shown in Fig. 3 (B). Note that apart from the LHC I, PSI-100 retains the reaction-center polypeptide subunits, P700 and the three iron-sulfur proteins, Le.,...
