Abstract

The primary photochemical events of photosynthesis occur in specialized, integral membrane proteins. The lightharvesting (LH) proteins collect photons and convey the resulting excitation energy to the reaction center (RC) proteins where charge separation occurs. Both LH and RC proteins generally contain several cofactors. Many of these cofactors are chiorophylls and carotenoids, which can be very selectively probed using resonance Raman (RR) spectroscopy at selected laser excitation wavelengths. The functional properties of these cofactors largely depend on their specific interactions within their protein host sites. RR spectroscopy uniquely permits a diagnosis of their conformations and molecular interactions, both in the resting and intermediate functional states of the protein
