The central importance of (bacterio)chlorophyll as a major photosynthetic pigment arises from its ability to both harvest the sunlight and perform ultrafast electron transfer (ET) reactions. The main function of the reaction center (RC) is to convert the photoexcitation in order to generate a trans-membrane potential in a series of ET steps. In bacterial RCs it is possible to relate molecular structure and biological function by exploring the early events after photoexcitation. In a series of ultrafast time resolved experiments with native and modi- fied samples, the details of the primary photosy nthetic reactions become visible, information on the relevant electron transfer parameters (free energy, reorganization energy and electronic coupling) can be deduced. This leads to a better understanding of architectural principles in photosynthetic RCs and optimization strategies in photosynthesis. [ABSTRACT FROM AUTHOR] |
