Mechanisms of the Early Steps in Bacterial Photosynthesis and Their Implications for Experiment

Abstract

The current situation on experiment and theory as regards the early electron transfer steps in bacterial photosynthesis is discussed. Recent experiments have limited the mechanistic possibilities, while an internal consistency test has limited the values of some parameters in the superexchange mechanism. The partitioning method has provided a useful and unified way of treating superexchange and other properties in these systems. The alternative reaction mechanisms have a number of consequences, and various experimental tests are considered or suggested.
