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


This article presents a brief historic account of the discovery of the electron acceptor P430 of green-plant Photosystem I (PS I) by optical spectroscopy. The spectro-kinetic and redox properties of P430 are described. A brief description of the recently-discovered P430 analogs, C-P430, in green-sulfur bacteria (Kusumoto et al., 1995) and its spectrokinetic properties are also included.
