Abstract
The aim is to determine how the functional kinetics of plastocyanin in the photosynthetic electron transport chain of oxygenic organisms depend on its own structure and those of its reaction partners, cytochrome f and photosystem I. Rapid electron transport through the system requires the evolutionary development of a balance between the rate of electron transfer and weak binding. Two interacting experimental approaches will be applied to proteins from plants and a cyanobacterium. The first will be to test the kinetic behaviour under a wide range of physical conditions; the second to probe the structural basis by a programme of site- directed mutagenesis based on the known structure of the plant complex cytochrome f plastocyanin.
