FTIR Studies of the Primary Electron Donor, P700

  • Jacques Breton
Part of the Advances in Photosynthesis and Respiration book series (AIPH, volume 24)


Over the last two decades FTIR difference spectroscopy has emerged as a prominent technique to investigate the electronic structure and the bonding interactions of P700, the primary electron donor of photosystem I. In this chapter, the advances in the field during this period are reviewed and discussed in the light of the structural model of P700 derived from X-ray crystallography. The effect on the FTIR difference spectra of mutations of the axial ligands of the chlorophyll molecules in P700 as well as of amino acid residues in hydrogen bonding interaction with the carbonyl groups of P700 is analyzed.
